DEVICE: MRIdian A3i Software (00850036816027)

An assembly of devices designed to produce high-energy electrons to yield high-energy x-rays used for therapeutic applications, primarily to treat cancer. It provides a uniform radiation field of uniform intensity and predictable energy level, in a beam with well defined dimensions. The principle of operation is linear acceleration of electrons by means of electromagnetic (EM) microwaves. The output is used as a treatment beam on the patient, either directly or after passing a suitable target. The system typically includes signal analysis and display devices, patient and device supports, and software.

A stationary assembly of computer-based devices designed to simultaneously create magnetic resonance imaging (MRI) images and deliver gamma radiation from a radionuclide source (typically cobalt) for stereotactic-radiosurgical therapy, typically to treat malignant tumours; the MRI images can be used to monitor treatment in real-time. It consists of radiation-emitting heads and collimators in a rotating gantry assembly; a magnet MRI system for soft-tissue imaging; patient couch and integrated positioning system; control consoles for image acquisition, planning and treatment administration; and integrated software.
