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.
