Abstract
A system to monitor a geometry of a treatment apparatus, an apparatus, a trackable assembly, program product, and methods are provided. The system includes a treatment apparatus having a radiation emitter, a rotating assembly controlled by a controller, and an application computer, which provides treatment delivery instructions to the controller. The system can also include a trackable assembly connected to the rotating assembly and having a fixedly connected first trackable body which functions as a reference fixture and a pivotally connected second trackable body which provides data used to determine a rotation angle of the rotating assembly. The system also includes an apparatus to track a trackable body which has a trackable body detector to detect a position of the indicators carried by the first and the second trackable bodies and a determiner to determine and verify the location of the origin of an isocenter coordinate system and to determine rotational path data about the rotating assembly.
