TREATMENT ROOM FIDUCIAL MARKER / CANCER THERAPY APPARATUS AND METHOD OF USE THEREOF

摘要

The invention comprises a fiducial marker-fiducial detector based treatment room position determination/positioning system apparatus and method of use thereof. Generally, a set of fiducial marker detectors detect photons emitted from and/or reflected off of a set of fiducial markers positioned on one or more objects in a treatment room and resultant determined distances and/or calculated angles are used to determine relative positions of multiple objects or elements in the treatment room. Position of the mapped objects is used in: (1) imaging, such as X-ray, positron emission tomogram, and/or proton beam imaging and/or (2) beam targeting and treatment, such as proton based cancer treatment. As relative positions of objects in the treatment room are dynamically determined using the fiducial marking system, engineering and/or mathematical constraints of a treatment beamline isocenter are removed.

1. A method for treating a tumor of a patient with positively charged particles, comprising the steps of:
providing a set of fiducial indicators, said set of fiducial indicators comprising:
a set of fiducial markers; anda set of fiducial detectors; placing said fiducial indicators on each of a set of objects in a treatment room, said set of objects comprising: (1) a nozzle system, said nozzle system connected to a synchrotron via a first beam transport line and (2) at least one of the patient and a patient positioning system; using said set of fiducial detectors to detect photons from said set of fiducial markers; determining, using a controller, a relative position of said nozzle system and the tumor using output from said set of fiducial detectors; and targeting the tumor, with the positively charged particles, using the relative position of said nozzle system and the tumor.
