Varian Linear Accelerators Offer Versatility

Varian’s Clinac and Trilogy medical linear accelerators are highly versatile radiotherapy treatment delivery machines that reportedly enable clinicians to pick the best treatment options from among a wide range of practical therapy choices. To enhance the effectiveness of radiotherapy treatments, Varian also offers real-time position management and exacting dose output — vital tools for achieving personalized cancer care and making cancer a manageable disease. Varian accelerators deliver the exact prescribed dose to the patient in the lowest number of monitor units (MUs) possible, according to the company. They incorporate high-resolution multileaf collimators for precise beam control so that the right dose is delivered to the right place at the right time. In addition, Varian offers one of the most comprehensive suite of image-guided radiotherapy (IGRT) tools: the On-Board Imager kV imaging device for cone-beam CT, radiographic, and fluoroscopic imaging, ultrasound, optical tracking, portal (MV) imaging and gating. Varian’s RapidArc radiotherapy technology makes it possible to use a Varian linac to deliver an advanced image-guided IMRT treatment with one 360 degree rotation around the patient, two to eight times faster than is possible with fixed-beam approaches or helical tomotherapy.

In addition, Varian has partnered with BrainLAB to offer the Novalis Tx radiosurgery platform, incorporating advanced imaging, treatment planning and treatment delivery technologies from both companies so clinicians can carry out highly precise, noninvasive image-guided radiosurgery procedures quickly and with great precision.
