  • Unified quality assurance for a radiation treatment delivery system
    Patent number: 7656998
    Abstract: A unified quality assurance technique to verify alignment of a radiation treatment delivery system. In one embodiment, a radiation treatment source is instructed to move to a preset source position. An image of the radiation treatment source at its actual source position is generated and compared against a reference image to determine whether the radiation treatment source correctly achieved the preset source position. In one embodiment, a positioning system is instructed to move a target detector to a preset target position. An image of the target detector at its actual target position is generated and compared against a reference target image to determine whether the positioning system correctly achieved the preset target position.

  • Phantom insert for quality assurance
    Patent number: 7594753
    Abstract: An apparatus for performing quality assurance on a radiation treatment delivery system includes a housing, a target region, and alignment protrusions. The housing is penetrable by a radiation beam of a radiation source of the radiation treatment delivery system and translucent to an image guidance system of the radiation treatment delivery system. The target region is disposed within the housing and contrasts with the housing when imaged by the image guidance system. The alignment protrusions are disposed on the housing for aligning a film insert relative to the target region.
