Method for combining proton beam irradiation and magnetic resonance imaging
First Claim
1. A method for treating a target within a body of a patient, said method comprising:
- irradiating a treatment volume having a known position;
supporting the patient such that the target is adjacent to the treatment volume;
scanning the body to monitor the position of the target;
selectively activating a radiating apparatus in response to the monitored position of the target to irradiate the target when the target is at least partially coincident with the treatment volume; and
selectively deactivating the radiating apparatus in response to the monitored position of the target when the target is not at least partially coincident with the treatment volume.

Abstract
A method which coordinates proton beam irradiation with an open magnetic resonance imaging (MRI) unit to achieve near-simultaneous, noninvasive localization and radiotherapy of various cell lines in various anatomic locations. A reference image of the target aids in determining a treatment plan and repositioning the patient within the MRI unit for later treatments. The patient is located within the MRI unit so that the target and the proton beam are coincident. MRI monitors the location of the target. Target irradiation occurs when the target and the proton beam are coincident as indicated by the MRI monitoring. The patient rotates relative to the radiation source. The target again undergoes monitoring and selective irradiation. The rotation and selective irradiation during MRI monitoring repeats according to the treatment plan.

10. A method for treating a target within a body of a patient with a proton beam radiating apparatus having a Bragg peak irradiating a treatment volume having a known position, said method comprising:
-
positioning the patient such that the target to be treated is located near the treatment volume;
scanning the body to determine the position of the target relative to the treatment volume;
activating the proton beam radiating apparatus to irradiate the target when the determined position of the target is at least partially coincident with the known position of the treatment volume; and
deactivating the proton beam radiating apparatus when the determined position of the target is not at least partially coincident with the treatment volume. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
