Abstract:
1. A system for use in radiation therapy of a lesion in a part of a patient comprising: a patient support table for receiving and supporting the patient during planning for and effecting of the therapy of the lesion; an immobilization device for locating the part of the patient on the table so as to remain fixed relative to the table during the planning and therapy; a magnetic resonance imaging system for obtaining MR images of the lesion of the patient including a magnet, at least one RF coil and an imaging control system; a CT imaging system for generating a 360 degree scanned image of the patient at the location of the lesion; a radiation therapy system for generating a beam of radiation for treatment of the Lesion and for scanning the beam 360 degrees around the lesion; the magnetic resonance imaging system, CT imaging system and the radiation therapy system being arranged at angularly spaced positions around the patient support table the magnetic resonance imaging system being arranged so as to provide relative movement between the table and the system to enable the imaging of the patient while the patient remains in fixed position relative to the table; the CT imaging system being arranged so as to provide relative movement between the table and the system to enable the imaging of the patient while the patient remains in fixed position relative to the table; the radiation therapy system being arranged so as to provide relative movement between the table and the system to enable the radiation treatment of the patient while the patient remains in fixed position relative to the table; the CT imaging system and the radiation therapy system being arranged so that the image and the treatment being arranged such that they lie in a common plane around the lesion in the patient; the table and immobilization device being MR compatible, radiation translucent, and non-conductive so as to allow the imaging and treatment of the patient while stationary on the table; and a treatment control system arranged to locate the lesion using the MR image and to plan the radiation treatment to vary the intensity of radiation around the plane using the CT image.
