BENEFITS OF IMAGE-GUIDED SURGERY<br />
CLINICAL BENEFITS The clinical benefits associated with<br />
image-guided surgery (IGS) continue to drive its acceptance and<br />
growth worldwide. IGS assists surgeons in performing less invasive<br />
surgeries through smaller incisions and direct access to<br />
specific targeted areas. Because image guidance promotes less<br />
invasive surgery, pati<strong>ent</strong>s in turn benefit. With BrainLAB <strong>system</strong>s<br />
being fully integrated into virtually any operating room via endoscope,<br />
microscope, ultrasound, and fluoroscope, the OR provides<br />
a complete surgical solution.<br />
FINANCIAL BENEFITS As medical technology advances, health<br />
care professionals are under increased pressure to improve the<br />
quality of health care as well as contain costs. Therefore, comprehensive<br />
knowledge of proper procedural billing and coding is<br />
ess<strong>ent</strong>ial when purchasing high-tech medical equipm<strong>ent</strong> such as<br />
image-guided surgery. Since reimbursem<strong>ent</strong> is becoming<br />
increasingly important for maximizing return on investm<strong>ent</strong>, it is<br />
a requirem<strong>ent</strong> to have access to the most curr<strong>ent</strong> coding procedures<br />
and laws. For this reason, BrainLAB has put a team of<br />
experts, dedicated to handling all reimbursem<strong>ent</strong> questions, at our<br />
customers’ disposal. A Reimbursem<strong>ent</strong> Help-Line further<br />
enhances our customer service.<br />
In addition, multiple software applications such as ENT,<br />
cranial, spine, knee, hip, and trauma can be installed on the<br />
same <strong>system</strong>. The <strong>system</strong> can be used in multiple departm<strong>ent</strong>s<br />
throughout the hospital, thus increasing cost-efficiency.

PATIENT REGISTRATION<br />
1�Select laser registration mode<br />
2�Scan surface with z-touch�<br />
laser pointer<br />
3�Verify registration accuracy
PATIENT IMAGING During diagnostic imaging, the pati<strong>ent</strong> is not<br />
required to wear a headset or fiducial markers. The scan is taken<br />
with a standard CT/MR protocol that ensures the optimum accuracy<br />
and resolution required for image-guided surgery. Because<br />
the CT/MR scan requires no headset or fiducial markers, the<br />
need for an additional scan once required to perform image-guided<br />
surgery is eliminated. This allows the surgeon to navigate<br />
within his/her original diagnostic imaging scan, thus reducing<br />
radiation exposure to the pati<strong>ent</strong>.<br />
ATTACHMENT OF THE REFERENCE HEADBAND BrainLAB’s<br />
Reference Headband is designed for usage in ENT and cranial<br />
navigation cases. The headband ensures dynamic pati<strong>ent</strong> tracking<br />
throughout the case and eliminates the need for invasive pati<strong>ent</strong><br />
immobilization or uncomfortable headsets. BrainLAB’s flexible<br />
VELCRO�- band adjusts smoothly to the pati<strong>ent</strong>’s head and fits all<br />
pati<strong>ent</strong> sizes. The innovative design avoids intra-operative shift and<br />
guarantees navigational accuracy throughout surgery.<br />
PATIENT REGISTRATION z-touch� laser registration forms<br />
the basis of BrainLAB’s headset-free scanning and registration.<br />
z-touch is a special laser pointer that allows to utilize each pati<strong>ent</strong>’s<br />
head and facial anatomy for registration. Once the pati<strong>ent</strong>’s facial or<br />
head surface is randomly scanned, BrainLAB’s advanced surfacematching<br />
algorithm quickly calculates pati<strong>ent</strong> registration.<br />
Physicians are able to accurately register pati<strong>ent</strong>s without using<br />
pati<strong>ent</strong> markers or headsets. Calculation errors, which may occur<br />
through landmark-point coordination, are therefore eliminated.<br />
INSTRUMENT CALIBRATION With BrainLAB’s redesigned<br />
instrum<strong>ent</strong> calibration matrix (ICM), the tip of extremely b<strong>ent</strong> or<br />
curved instrum<strong>ent</strong>s can easily be calibrated for use in navigation.<br />
Calibration is quickly achieved by affixing the desired instrum<strong>ent</strong><br />
with one of BrainLAB’s wireless instrum<strong>ent</strong> adaptor clamps and<br />
then touching the tip of the surgical instrum<strong>ent</strong> to one of the two<br />
pivot points on the ICM. The software automatically calculates<br />
the exact location of the instrum<strong>ent</strong>’s tip and the instrum<strong>ent</strong> is<br />
ready for navigation. In addition, the instrum<strong>ent</strong>’s shape and<br />
diameter can also be calibrated by inserting the shaft of the<br />
instrum<strong>ent</strong> into the holes of the ICM.<br />

KOLIBRI ENT SYSTEM<br />
The Kolibri <strong>system</strong> was designed with the goal of making image-guided surgery available to every pati<strong>ent</strong>. Since Kolibri<br />
ENT is compact and affordable it is ideal for surgery c<strong>ent</strong>ers and for hospitals with smaller case loads or hospitals in<br />
need of additional treatm<strong>ent</strong> capacity. The <strong>system</strong>’s lightweight portable design makes it easy to move between multiple<br />
facilities. With the ability to track pre-existing surgical instrum<strong>ent</strong>s, to display live endoscopic video, and to control the<br />
<strong>system</strong> via the touchscreen monitor, Kolibri’s integration into the surgical procedure is straightforward. Driven by<br />
BrainLAB’s user-friendly software, the learning curve of the <strong>system</strong> is extremely short.<br />
LOADING OF PATIENT DATA Pati<strong>ent</strong> data will be automatically<br />
loaded upon data transfer completion. Using the hospital’s network<br />
connection and the universal DICOM format, the new software<br />
PatXfer assures a simple and time-saving data transfer.<br />
Data on the scanner can be accessed and easily retrieved.<br />
PATIENT SETUP BrainLAB’s Reference Headband is attached<br />
to the pati<strong>ent</strong>’s head ensuring dynamic tracking throughout the<br />
case and eliminating the need for invasive pati<strong>ent</strong> immobilization<br />
and uncomfortable headsets. This dynamic reference device<br />
allows for unpreced<strong>ent</strong>ed freedom of movem<strong>ent</strong> during navigation<br />
while maintaining a high degree of accuracy.<br />
PATIENT REGISTRATION Equipped with the standard wireless<br />
Softouch pointer the pati<strong>ent</strong> is easily registered within seconds.<br />
The pointer uses a sensitive tip to detect the surface points on<br />
the pati<strong>ent</strong>’s skin. For additional intra-operative registration, other<br />
methods such as the z-touch� laser are also compatible with the<br />
<strong>system</strong>.<br />

VECTORVISION ® ACCESSORIES<br />
BrainLAB offers a wide variety of accessories, which complem<strong>ent</strong> the VectorVision ENT and Kolibri ENT<br />
image-guided surgery <strong>system</strong>s. With BrainLAB’s industry-leading, pat<strong>ent</strong>ed passive marker technology, the<br />
surgeon can navigate instrum<strong>ent</strong>s with an unequalled degree of freedom. The wireless design eliminates<br />
cables, foot switches, and other restricting electronics. Each hardware compon<strong>ent</strong> and accessory is highly<br />
refined and engineered for optimum efficiency, durability, and ease of use.<br />
POINTERS The universal VectorVision instrum<strong>ent</strong>, the Pointer, can<br />
be used for multiple tasks, from pati<strong>ent</strong> registration and accuracy<br />
verification to navigation for surgical resections. VectorVision<br />
Pointers are lightweight, durable and available both sharp- and<br />
blunt-tipped, depending on the specific surgical requirem<strong>ent</strong>s. The<br />
passive markers are attached to the Pointer via simple threads, and<br />
ensure almost unlimited maneuverability, minimizing line of sight<br />
issues. BrainLAB’s reflective marker spheres can be purchased as<br />
pre-sterilized disposables or re-sterilizable for repeated use.<br />
INSTRUMENT ADAPTERS With BrainLAB’s passive marker<br />
instrum<strong>ent</strong> adapter clamps, virtually any pre-existing ENT instrum<strong>ent</strong><br />
– such as blakesly forceps, suction, microdebreeders, and<br />
curettes can be integrated into the procedure. The small, lightweight<br />
adapter clamps are easily attached via a thumbscrew and<br />
stay rigidly affixed throughout the case. Due to the unlimited ability<br />
to interchange the differ<strong>ent</strong>ly sized clamps and arrays, the surgeon<br />
has access to the right instrum<strong>ent</strong> at the right time.<br />
INSTRUMENT CALIBRATION MATRIX (ICM) In addition to an<br />
instrum<strong>ent</strong> tip calibration, BrainLAB offers an easy, fast, and accurate<br />
calibration of instrum<strong>ent</strong> diameter and vector. Within seconds,<br />
BrainLAB’s ICM integrates uniquely shaped instrum<strong>ent</strong>s such as<br />
frontal sinus probes and suctions. The ICM expands the range of<br />
instrum<strong>ent</strong>ation, which can be incorporated into navigated surgery.<br />
SKULL REFERENCE ARRAY BrainLAB’s bone-anchored<br />
Reference Star has been developed for usage in surgeries of the<br />
lateral skull base and other complex ENT/neurosurgical procedures.<br />
This dynamic reference device allows for unpreced<strong>ent</strong>ed<br />
freedom of movem<strong>ent</strong> during navigation while maintaining<br />
BrainLAB’s high degree of accuracy. The Skull Reference Array<br />
is a minimally invasive device that is directly attached to the<br />
outer skull with a small self-taping screw. Three support pins stabilize<br />
the fixation of the base. Since the surgeon does not have<br />
to rely on fixed reference units like the Mayfield Clamp the head<br />
of the pati<strong>ent</strong> can be moved freely during surgery to provide better<br />
access to the areas of interest.
IMAGE COMPOSER BrainLAB’s Image Composer opens a new<br />
dimension in the intra-operative visualization of diagnostic<br />
images. Multi-modality image data can be merged into one unified<br />
image. Information is automatically extracted and displayed<br />
in this new image set to optimize the visualization of preferred<br />
structures such as bone, vessel, and tissue, making all relevant<br />
data available at a glance. Image Composer is the ideal software<br />
package for the otolaryngologist who performs surgical procedures<br />
at the skull base.<br />
MICROSCOPE INTEGRATION VectorVision Microscope<br />
Integration increases the functionality of the navigation <strong>system</strong><br />
and microscope, while at the same time optimizing the workflow<br />
of both applications. By easily attaching BrainLAB’s specially<br />
designed microscope adapter the microscope can be used to<br />
navigate within a matter of seconds. Intellig<strong>ent</strong> features such as a<br />
virtual pointer, image injection and video display ensure that the<br />
surgeon receives the best visual information when integrating a<br />
microscope into the navigation <strong>system</strong>.<br />
IGS-READY POINTER INSTRUMENTS The newly designed<br />
pointer instrum<strong>ent</strong> set provides surgeons with a number of various<br />
interchangeable tip shapes, ensuring maximum navigation flexibility<br />
while maintaining high intra-operative precision throughout<br />
surgery. The surgeon has the freedom to choose whatever tip is<br />
appropriate for the scheduled indication.<br />
The tips can be aligned and fixed in eight differ<strong>ent</strong> ori<strong>ent</strong>ations<br />
making it easy to adjust the instrum<strong>ent</strong> to the surgical setting. The<br />
probe has an integrated StarLink interface for the adaptation and<br />
wireless tracking of the pointer in combination with an Instrum<strong>ent</strong><br />
Adapter Array.<br />
IGS-READY SUCTION Standard suction devices are equipped<br />
with the new StarLink interface providing the highest navigation<br />
accuracy possible. Once the adaptor clamp is attached, calibration<br />
is performed instantly.<br />

PATIENT HISTORY The pati<strong>ent</strong>, a 42-year-old female with a history<br />
of motor vehicle accid<strong>ent</strong>, in which she suffered severe<br />
frontal and naso-facial trauma. This included severely comminuted<br />
frontal sinus facture and naso-orbito-ethmoid fracture. This was<br />
repaired with extensive frontal bone and trans-nasal wiring. Ten<br />
years later the pati<strong>ent</strong> developed Pott’s puffy tumor. This was<br />
managed by a prolonged course of antibiotics, and endoscopic<br />
drainage of the frontal recess and frontal sinus to the midline utilizing<br />
a drill (Draf IIB procedure). At the time of the procedure,<br />
16<br />
CHRONIC FRONTAL SINUSITIS WITH COMPLICATED<br />
ANATOMY<br />
Fig.1 Fig.2<br />
Fig.3 Fig.4<br />
VECTORVISION ® CASE REPORTS<br />
the frontal recess exposure was carried to the limits of the<br />
instrum<strong>ent</strong>ation, but an area of neo-osteogenesis and narrowing<br />
remained laterally. Postoperatively, the inflammation was noted<br />
to dramatically improve and the pati<strong>ent</strong> became and remained<br />
asymptomatic. However, over the subsequ<strong>ent</strong> years the pati<strong>ent</strong><br />
developed endoscopic evidence of bony closure of the communication<br />
to the lateral portion of the frontal sinus.<br />
This endoscopically diagnosed bony stenosis of the lateral aspect<br />
of the frontal recess was confirmed by CT imaging, which also<br />
demonstrated the extensive hardware pres<strong>ent</strong> from her previous<br />
injury. Notably, the lateral portion of the right frontal sinus was<br />
opacified, and this area was closed off from the remaining sinus<br />
cavity and frontal recess by neo-osteogenic foci. On preoperative<br />
endoscopy, normal landmarks could not be visualized in light of the<br />
pati<strong>ent</strong>’s previous trauma and surgery.<br />
TREATMENT Endoscopic frontal sinusotomy with removal of the<br />
obstructing bone was recommended, and the pati<strong>ent</strong> cons<strong>ent</strong>ed to<br />
proceed. Stereotactic navigational imaging was obtained using the<br />
BrainLAB protocol. Endoscopically, two depressions were visualized<br />
within the pot<strong>ent</strong>ial frontal drainage tract (Fig.1). Intra-operative<br />
navigational imaging using the BrainLAB VectorVision ENT <strong>system</strong><br />
demonstrated the more medial recess to be the skull base (Fig.2),<br />
while the lateral recess correlated with the likely drainage pathway<br />
(Fig.3). These determinations were visualized in three dimensions.<br />
Using a combination of markedly angled, powered diamond<br />
burrs, frontal recess curettes, and forceps with angles designed<br />
for frontal sinus surgery, sinusotomy was performed. Thick bone<br />
was removed. A curved suction equipped with a BrainLAB<br />
instrum<strong>ent</strong> adaptor clamp was calibrated and passed into the<br />
sinus, confirming patency in three dimensions (Fig.4).<br />
CONCLUSION Throughout the procedure, because of the optical<br />
referencing of the <strong>system</strong>, no accuracy problems were encountered<br />
secondary to the metallic hardware pres<strong>ent</strong> in the surgical<br />
vicinity. Postoperatively, the pati<strong>ent</strong> has done well, with excell<strong>ent</strong><br />
trans-illumination of the sinus observed during office endoscopy.<br />

MINIMALLY-INVASIVE PITUITARY SURGERY (MIPS)<br />
PATIENT HISTORY A 56-year-old man was found confused in<br />
the local park. On pres<strong>ent</strong>ation to the emergency room, he was<br />
found to be ori<strong>ent</strong>ed to person and place, but not time.<br />
Toxicology screening was normal. MRI of the head was obtained<br />
with findings of a large compressing mass of the sella with v<strong>ent</strong>ricular<br />
enlargem<strong>ent</strong> (Fig. 1) consist<strong>ent</strong> with a large pituitary adenoma.<br />
TREATMENT He was taken to the operating room where endoscopic<br />
resection of the sellar tumor was performed via minimallyinvasive<br />
pituitary surgery (MIPS) technique. Image guidance<br />
utilizing BrainLAB VectorVision was utilized to assist in the resection.<br />
The head was not pinned, being allowed to move freely using<br />
the adjustable headband reference array for head localization<br />
while using the <strong>system</strong>. Registration was performed utilizing the<br />
touchless z-touch� registration technique. Instrum<strong>ent</strong>s, including<br />
angled open curettes, were tracked actively during the surgery,<br />
allowing for real-time assessm<strong>ent</strong> of instrum<strong>ent</strong> position (Fig. 2).<br />
This allowed maximum tumor resection while minimizing risk to<br />
the pati<strong>ent</strong>.<br />
CONCLUSION No CSF occurred. Pathologic examination<br />
revealed pituitary adenoma. Post-op MRI shows very complete<br />
tumor resection (Fig. 3).<br />

BRAINLAB’S PRODUCTS<br />
BrainLAB offers a large and diversified portfolio of unique and superior products for various medical subspecialties.�Image-guided<br />
surgery enables the physician to track the position of a surgical instrum<strong>ent</strong> or implant<br />
to guide it safely and precisely to its target.�Radiosurgery enables the non-invasive treatm<strong>ent</strong> of various<br />
tumors using focused radiation.<br />
VectorVision 2<br />
ExacTrac X-ray<br />
VECTORVISION� CRANIAL With VectorVision cranial, neurosurgeons<br />
have the ability to track the position of virtually any surgical<br />
instrum<strong>ent</strong> equipped with BrainLAB’s passive markers. Instrum<strong>ent</strong>s<br />
are continuously visualized relative to pre-operative diagnostic<br />
images, giving surgeons the ability to see beyond the surface of<br />
the surgical field using computer renderings. VectorVision cranial<br />
provides safer and less invasive access to brain tumors, vascular<br />
abnormalities, and other intra-cranial targets by minimizing the<br />
size of craniotomies.<br />
VECTORVISION� SPINE VectorVision spine gives surgeons<br />
the ability to interactively select the ideal size and 3-dimensional<br />
position of a pedicle screw in a virtual reality display. The surgeon<br />
can then track his/her drill or awl in order to align it with the preplanned<br />
pathway of the screw. VectorVision spine contributes to<br />
lowering the risk of misplacem<strong>ent</strong> of screws and the complications<br />
that can occur such as a failed fusion.<br />
VECTORVISION� KNEE As VectorVision knee does not require<br />
diagnostic images or pre-operative planning, the <strong>system</strong> is a time<br />
and cost-effici<strong>ent</strong> solution, which can be used for every total<br />
knee replacem<strong>ent</strong> procedure. Using the VectorVision navigation<br />
<strong>system</strong> for a total knee replacem<strong>ent</strong> ensures more precise<br />
implantation of the prosthesis. The implant lifetime can thus be<br />
pot<strong>ent</strong>ially increased and the need of early revision surgeries<br />
considerably reduced.<br />
VECTORVISION� HIP With VectorVision hip, surgeons have the<br />
ability to semi-automatically select the perfect size and shape<br />
of an implant based on pre-operative 3-dimensional CT data of<br />
the respective pati<strong>ent</strong>. Leg length and range of leg movem<strong>ent</strong><br />
are simulated, ensuring the optimum implant is selected and set.<br />
During the surgical procedure, the surgeon is able to guide<br />
his/her saws, drills, and reamers to ensure correct implant placem<strong>ent</strong><br />
is carried out according to plan.
VECTORVISION� TRAUMA VectorVision trauma has been specially<br />
designed for trauma and emergency cases and offers intuitive<br />
navigation on bone structures. Based on navigation in intra-operative<br />
fluoroscopic images, VectorVision trauma supports the treatm<strong>ent</strong><br />
of fractures with interlocking nails and screws and therefore<br />
significantly reduces radiation exposure for pati<strong>ent</strong> and surgeon.<br />
BrainSCAN With BrainSCAN software, surgeons and physicists<br />
are able to outline tumors and critical structures on CT and MR<br />
images and then reconstruct all data in a 3-dimensional model. This<br />
3-D model is then used to establish the physical and geometric parameters<br />
of direct radiation beams to be aimed at the tumor. The goal<br />
is to minimize the dose received by critical structures while maximizing<br />
the dose received by the tumor. The “IMRT” option further automatizes<br />
the planning process while refining the dose distribution.<br />
NOVALIS� Novalis, BrainLAB’s dedicated <strong>system</strong> for non-invasive<br />
stereotactic radiosurgery and radiotherapy (SRS/SRT),<br />
repres<strong>ent</strong>s cutting-edge technology for highly precise treatm<strong>ent</strong>s<br />
of brain as well as head & neck tumors, arteriovenous malformations<br />
and certain functional disorders. Novalis Body features<br />
image-guided radiosurgery for high precision treatm<strong>ent</strong> of body<br />
targets. Based on its X-ray localization technology tumors can be<br />
localized with sub-millimeter accuracy and pati<strong>ent</strong>s can be positioned<br />
automatically and with a higher degree of precision. With<br />
Novalis Body, treatm<strong>ent</strong>s for spine, lung, liver and other body<br />
lesions can be carried out quickly and effici<strong>ent</strong>ly.<br />
m3� BrainLAB’s high-resolution multileaf collimator with its fine<br />
3 millimeter leaves has revolutionized radiosurgery by introducing<br />
conformal treatm<strong>ent</strong> techniques that allow the dose to be precisely<br />
tailored to the shape of the tumor. The reduced irradiation<br />
of normal tissue and the homogeneous dose distribution within<br />
the PTV contributes to superior and effici<strong>ent</strong> pati<strong>ent</strong> care.<br />
ExacTrac� X-ray The high-resolution x-ray imaging module features<br />
clinically-implem<strong>ent</strong>ed Image Guided Targeting as an upgrade<br />
for existing Linacs. The high quality imaging of internal structures<br />
and organs results in an extremely accurate setup of the target<br />
volume and overcomes the limitations of conv<strong>ent</strong>ional pati<strong>ent</strong><br />
positioning methods that are based on external skin markers.<br />
