Varian's On-Board Imager (OBI) offers three imaging modalities that make it possible to locate the targeted tumor every day prior to treatment, note any changes in tumor size, shape, or position, and track tumor motion in order to enhance treatment precision. The On-Board Imager provides kV imaging at treatment and includes radiographic, fluoroscopic and optional cone-beam CT image acquisition and patient repositioning applications. Read more...
Physiological functions, such as respiration, can change the tumor position during treatment, requiring the use of a larger treatment volume to compensate for tumor movement. The RPM Respiratory Gating system synchronizes delivery of treatment with respiration motion, allowing minimization of motion margins. Read more...
PortalVision aS500-II and aS1000 use the latest amorphous silicon imaging technology to produce the high-quality MV images needed for accurate patient positioning and tumor localization. Our fully retractable Exact™ arm provides a wide range of movement, facilitating setup for complex treatment techniques. Read more...
The Exact IGRT Couch Top has been designed to facilitate radiographic, fluroscopic, and CBCT-guided therapies. Manufactured from robust carbon fiber, and free of metal and other artifact-creating materials, the IGRT couch top provides significantly improved images and more precise image matching. Read more...
The SonArray module is an advanced, high-precision patient-positioning platform designed for IMRT radiation therapy. SonArray integrates infrared SRS/SRT optical tracking devices with 3D ultrasound reconstruction technology to position the patient so that for each fraction, the internal target is precisely at isocenter.
