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