Abstract
A method and apparatus for positioning a patient for radiation treatment are described. The method includes obtaining a plurality of projection images of a patient positioned on a treatment couch, displaying at least one of the plurality of projection images with a corresponding synthetic projection image on a display, adjusting the position of the at least one projection image on the display to approximately align with the corresponding synthetic projection image in response to a user dragging the at least one projection image on the display with a user interface device, and moving the treatment couch to position the patient based on position adjustments of the at least one projection image.
Claims20
A computer-implemented method comprising:
- obtaining a plurality of projection images of a patient positioned on a treatment couch;
- displaying at least one of the plurality of projection images with a corresponding synthetic projection image on a display;
- adjusting the position of the at least one projection image on the display to approximately align with the corresponding synthetic projection image in response to a user dragging the at least one projection image on the display with a user interface device;
- and
- moving the treatment couch to position the patient based on position adjustments of the at least one projection image.
A computer-readable storage medium having instructions stored thereon that, when executed by a treatment delivery system, cause the treatment delivery system to perform a method, comprising:
- receiving a plurality of projection images of a patient positioned on a treatment couch;
- displaying at least one of the plurality of projection images with a corresponding synthetic projection image on a display;
- adjusting the position of the at least one projection image on the display in response to a user dragging the at least one projection image on the display with a user interface device;
- and
- transmitting treatment couch positioning data based on position adjustments of the at least one projection image.
A treatment delivery system comprising:
- a display;
- a user interface device;
- a memory;
- and
- a processing device operatively coupled with the display, the user interface device and the memory to
- obtain a plurality of projection images of a patient positioned on a treatment couch;
- display at least one of the plurality of projection images with a corresponding synthetic projection image on the display;
- adjust the position of the at least one projection image on the display in response to a user dragging the at least one projection image on the display with a user interface device;
- and
- move the treatment couch based on position adjustments of the at least one projection image.
