  • Method and apparatus for patient loading and unloading
    Patent number: 8402581
    Abstract: A method and apparatus of a positioning system are described to position an upper-half of a body relative to a head-end of a couch. The positioning system may be a patient positioning system and may include a treatment couch, a leg rest coupled to the treatment couch, and a drive mechanism coupled to the leg rest. The patient positioning system may also include a treatment couch, having a base portion of a treatment couch and plurality of detachable portions of the treatment couch. The plurality of detachable portions to adjust a height of the treatment couch to accommodate differing heights of patients.

  • Determining a target-to-surface distance and using it for real time absorbed dose calculation and compensation
    Patent number: 7505559
    Abstract: An apparatus and method for determining a target-to-surface distance (TSD) between a target region in a body and an actual point of entry of a radiation beam into the body from a radiation source. The method may include determining an absorbed dose of radiation from the radiation beam at the target region using the TSD. The method may also include compensating for both the motion of the target region with respect to the radiation source, and the motion of surrounding tissue relative to the target region. The apparatus may include a sensor system to determine the actual point of entry of the radiation beam into the body.
