MVision, from Siemens Medical Solutions, is a volumetric in-line target imaging solution and the natural next step in Image-Guided Radiation Therapy (IGRT). Designed to work with Siemens’ linear accelerators, the system is the first commercial implementation of cone-beam technology utilizing a standard radiotherapy treatment beam. MVision makes it possible for the megavoltage (MV) source used for treatment to also create a 3-D image of the patient, enabling clinicians to “see inside” the patient at the most appropriate moment.
MVision fully integrates and automates all processes, including acquisition, reconstruction, registration, assessment, patient positioning and clinical review. With a few steps, therapists can calculate 3-D offsets, send them to the treatment couch to compensate for daily variations and safely deliver therapy.
The solution does not require an independent imaging source for IGRT, thus maximizing clinical accessibility and patient comfort. This innovation also frees caregivers from performing unnecessary electromechanical maintenance, so they can focus on patient care.
