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.
