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.
