Image guided radiotherapy (IGRT) provides high-resolution 3D images to pinpoint tumour sites, adjust the patient positioning when necessary and complete a treatment—all within the standard treatment timeslot. These capabilities take IMRT and stereotactic IMRT technologies one step further by raising the quality of the patient care and improving efficiency. IGRT technology accounts for motion to ensure that the target is in the same position every treatment session. With IGRT, innovative radiographic, fluoroscopic and cone-beam CT modes are integrated with automated-repositioning and motion-management visualisation software. This enables clinicians to verify that treatments are completely in sync with respiration.
IGRT from Varian Medical Systems offers clinicians advanced imaging techniques to verify the patient position and tumour position at the time of treatment. Knowing exactly where the tumour is allows clinicians to reduce the volume of tissue that is irradiated, so they can target only the tumour and spare the surrounding normal tissue. To help address the issue of tumour movement during treatment, Varian has pioneered IGRT technology, and developed fully integrated, customisable solutions designed to meet the needs of growing clinics, and to help doctors raise the quality of the patient care. Varian’s IGRT solutions including our treatment couch, the Eclipse treatment-planning system and treatment-delivery systems including the Edge-, TrueBeam-, Trilogy- and Clinac-series linear accelerators, support all stages of treatment—from planning to treatment delivery to health-record management.
