  • Systems and methods for evaluating motion tracking for radiation therapy
    Patent number: 10881877
    Abstract: An apparatus includes: a processor configured for obtaining a first image that corresponds with a first multi-leaf collimator (MLC) configuration, wherein the first image is generated when the MLC is stationary, obtaining a second image that corresponds with a second MLC configuration, wherein the second image is generated when the MLC and/or another component of a radiation machine is being operated to track a motion, and performing an analysis based at least in part on the first image and the second image to obtain a result; and a non-transitory medium for storing the result.
    Type: Grant

  • System and method for patient-specific motion management for treatment
    Patent number: 10500418
    Abstract: An apparatus for assisting a selection of motion management technique for use with a treatment machine having an energy source, comprises: one or more input for obtaining motion trace of a target to be treated, and/or for obtaining motion data of a fiducial; and a motion management processor configured to determine motion management data based at least in part on at least a portion of the motion trace of the target and/or at least a portion of the motion data of the fiducial, wherein the motion management data indicates desirability and/or undesirability of one or more motion management option(s); wherein the motion management processor is also configured to output the motion management data for assisting the selection of the motion management technique for use with the treatment machine.

  • OPTICAL SYSTEM FOR RADIATION TREATMENT
    Publication number: 20190105514
    Abstract: An apparatus includes: a structure for coupling to a patient; a plurality of reflective markers coupled to the structure, wherein the reflective markers are configured to reflect non-visible light; and a securing mechanism configured to secure the structure relative to the patient. An apparatus includes: a first light source configured to project a first structured light onto an object, wherein the first structured light is non-visible; a first camera configured to obtain a first image of the first structured light as projected onto the object; a second camera configured to obtain a second image of the first structured light as projected onto the object; and a processing unit configured to process the first and second images from the first camera and the second camera; wherein the first camera and the second camera are configured for non-visible light detection.
