At the heart of the ViewRay™ system is a custom-designed MRI unit that can capture volumetric soft-tissue images in just a few seconds. MRI is the clinically preferred method of imaging soft tissue: unlike CT imaging, MRI provides high-contrast images without exposing the patient to unnecessary ionizing radiation.
Volumetric MR imaging can be used for planning and daily positioning as well as for precision targeting during treatment. Prior to treatment, MRI assists in accurate patient setups without interrupting conventional workflows. Volumetric pretreatment images deliver:
Once a pretreatment image is captured, the ViewRay system can rigidly register the image of the moment with the treatment planning image. In addition, the system offers extremely fast deformable registration capabilities, enabling accurate positioning—all within the typical workflow.
