Abstract: A method of calibration in a radiation delivery system. The method including acquiring, using a camera, an image of a radiation beam incident on a phantom, wherein the radiation beam being emitted by a radiation source of the radiation delivery system and the phantom comprising an X-ray luminescent material. The method further including determining a beam pointing offset based on the image. The method further including calibrating a position of the radiation source of the radiation delivery system based on the beam pointing offset and a relative position of the camera with respect to a beam axis of the radiation beam.

Abstract: A radiation treatment system is described, including a linear accelerator (LINAC), having a housing, to emit a treatment beam to a target location and a Cerenkov emission detector, coupled to the housing of the LINAC, to capture a set of images of optical Cerenkov emission generated at the target location by charged particles of the treatment beam. A method is described including emitting the treatment beam from the LINAC to the target location and capturing, using the Cerenkov emission detector coupled to the LINAC, the set of images of optical Cerenkov emission generated at the target location by the treatment beam.

Abstract: An interface is provided to a user to perform a plurality of treatment planning operations associated with the treatment plan before the treatment plan is optimized. The treatment planning operations include at least one of selecting a treatment planning parameter or inputting data corresponding to the treatment planning parameter. One or more templates containing one or more pre-defined treatment planning parameters are provided to the user to enable the user to skip performing one or more of the plurality of operations.

Abstract: An apparatus and method for optimizing a workspace of a radiation treatment delivery system. An optimized treatment plan is generated for delivering a dose of radiation to a volume of interest (“VOI”) in a patient using fewer changes to a treatment plan parameter during delivery of the dose of radiation then available to a radiation treatment delivery system. The optimized treatment plan limits a number of adjustments to the treatment plan parameter during delivery of the dose of radiation. Prior to delivery, the optimized treatment plan is analyzed to determine whether a quality of the optimized treatment plan is acceptable.
