ACCOUNTING FOR TIME AND MOVEMENTTARGETED TREATMENTSThe right timeClinicians can trust that Varian systems will deliver treatment at theright time, the instant that the tumor is on target. Whether it’sday-to-day repositioning of the patient or managing motion thatoccurs during treatment, Varian has developed the necessary DynamicTargeting IGRT process tools: cone-beam CT, radiographic, fluoroscopic,ultrasound, optical and gating. With Varian systems you can personalizethe care for each patient based on that patient’s condition and yourindividual clinical protocol.BREAST, RESPIRATORY GATING. Better targeting of dose.Varian systems provide respiratory gating and fluoroscopic field verificationof the tumor’s exact pretreatment location. These technologies effectively“freeze” the motion caused by a patient’s breathing during treatment.The heart is protected from unnecessaryradiation during breast treatment with theRPM respiratory gating system.“For some women, when we use standard breast tangent techniques,a fair bit of cardiac volume gets encompassed in the treatment field,” saysFrancine Halberg, MD, Marin Cancer Institute, Greenbrae, CA, “We havemade a commitment to our breast cancer patients to no longer treat theirhearts.”Tumors change position, both during andbetween treatments. With image-guidedradiotherapy (IGRT), clinicians must be ableto quickly reposition patients relative to both thenew tumor location and the machine’s isocenter.Cone-beam CT images are acquired to accountfor inter-fraction movement of the patient,based upon the positioning of soft tissues,while Varian’s RPM respiratory gating systemkeeps track of intra-fraction movement.“IGRT will be especially important for ensuring aprecision treatment, particularly when we areperforming IMRT and/or escalating the dose.”Fang-Fang Yin, PhD, Director of Medical PhysicsDuke University Medical Center, Durham, NCHEAD AND NECK. Position, verify, monitor quickly.The use of cone-beam CT with automated matching allows fastrepositioning of head and neck patients. And with infrared opticaltechnology, secondary setup verification and patient positionmonitoring can be done during treatment.PROSTATE. All the right tools.Prostate lesions can be positioned using optically guided, infrared-basedpositioning with ultrasound images. Ultrasound-based guidance permitsmore accurate positioning of the prostate under the beam compared totraditional positioning methodology.Using Varian’s On-Board Imager, 3D - 3Dcone-beam CT image registration facilitatesaccurate day-to-day patient positioning.Specialized IGRT tools add tocomprehensive treatment options.Here, guided prostate localizationpermits accuracy.
Designed to follow your workflow,Varian’s advanced monitoring andcontrol console displays optimalviews of the treatment target and other vitalinformation. Patients can be repositionedautomatically at the touch of a button tomaintain exact alignment of tumor andradiation beam.“Implementing new technology requires aninformation infrastructure that supports allcapabilities—and does so efficiently. WithVarian’s 4D console and Inspirationenvironment, we have been able to reduce setupand treatment times on the order of 30 percent.”Randy Holt, PhD, Chief Medical PhysicistEnloe Medical Center, Chico, CAEFFICIENT AUTOMATIONVarian software-driven delivery systems represent the zenith ofinnovation in cancer care, while maintaining rigorously highstandards for patient safety. And with each automation innovation,Varian has compressed treatment times so that you can treat more patientseffectively every day. Using Varian tools, for example, clinicians can nowaccomplish sophisticated IGRT and IMRT in a normal treatment window.There’s more:DART (Dynamic Adaptive Radiotherapy).Optimal treatment at the moment of care.For the first time, dynamic adjustments at the treatment console are notonly possible, but practical. DART is the seamless convergence of advancedIMRT, IGRT and dose guidance. Its powerful information platform lets youimmediately integrate up-to-the-second patient information, interpretthat information and adapt dose and delivery on the spot.Argus® IMRT assures fast trackingof MLC performance.FAST, AUTOMATED QA. Minutes instead of hours.Complex treatment techniques require efficient automation of qualityassurance processes. With Varian’s Argus® and Portal Dosimetry applications,rigorous QA can be done with confidence in minutes, not hours. Machine QA,IMRT plan verification and dose guidance are all supported.FULL-MOTION ROBOTICS. Arms move for optimal views.Full-motion robotically controlled arms automatically position Varian’sOn-Board Imager kV imaging system to render optimal tumor views whilemaintaining coincidence between imaging and treatment isocenters. Varianrobotics, software and remote couch all work in unison to make the IGRTprocess efficient and clinically practical for cancer patients.Once the patient is on the treatment couch,everything can be done from outside thetreatment room.TREATING MORE PATIENTS, MORE EFFICIENTLYREMOTE COUCH CONTROL. Simplifying workflow.Enhancing treatment accuracy while maximizing clinical efficiency, Varian’sExact Couch can be moved remotely with great precision, simplifyingpatient positioning and improving workflow. It uses a patented IndexedImmobilization patient-positioning system to minimize patient setup times.Command center aids high-resolution monitoringand efficient treatment decisions: one keyboard,one mouse and all the information necessary atone glance.
