Abstract: Systems and methods of tracking location of an internal bodily structure of a patient in a radiation treatment room, including a fiducial marker having a unique center point, an offset structure detachably connected to the fiducial marker, the offset structure having unique three dimensional offset coordinates relative to the center point, a means for detachably mounting the offset structure to the patient, an imaging unit to measure location information of the offset structure relative to a target internal bodily structure of the patient, and a detection unit to detect location information of the offset structure and to calculate an offset distance between the target internal bodily structure and the center point.

Abstract: An operator positioning apparatus for a proton treatment system includes: a proton beam nozzle to emit a proton beam to a targeted region of a patient; a gantry wheel having a front face to support the proton beam nozzle to direct the proton beam to an isocenter of the gantry wheel corresponding to a center of the targeted region, wherein the gantry wheel rotates the proton beam nozzle around the isocenter; an active floor that horizontally translates across the front face of the gantry wheel, the active floor having an opening having a width through which the proton beam nozzle protrudes when the proton beam nozzle is located below the targeted region.

Abstract: A gantry apparatus for a proton treatment system, including a proton beam nozzle to emit a proton beam to a targeted region of a patient, a gantry wheel to support the proton beam nozzle to direct the proton beam to an isocenter of the gantry wheel corresponding to a center of the targeted region, a plurality of adjustable bearings incrementally spaced apart along an outer diametrical surface of the gantry wheel, and a bearing surface to support a portion of the adjustable bearings such that when the wheel is rotated from a first angular position to a second angular position, at least a portion of the bearings contact the bearing surface to raise or lower the gantry wheel to realign the proton beam to the center of the targeted region.

Abstract: Treatment volume projection systems and methods for use in treating patients, including an image scanner to capture an image of a patient's treatment volume, a processor to process the image to generate a treatment volume image corresponding to at least a portion of the treatment volume, and an image projector to project the treatment volume image onto a projection surface. The treatment volume image can include an x-y scanning area of the treatment volume to assist delivery of treatment to the patient.
