A system to analyze the geometry of a radiation treatment apparatus, software, and methods are provided. The system includes an apparatus having a rotating assembly and a trackable body or plurality of trackable bodies, to mark a location of a preselected portion of the rotating assembly. The system also includes a trackable reference fixture and can include a constant orientation trackable body. A determiner determines the position and/or orientation of the trackable bodies, the trackable reference fixture, and constant orientation trackable body. The determiner then determines the geometry of the treatment apparatus to analyze a coordinate system used by an operator. The determiner can have a memory and geometry analyzing software stored in the memory to analyze the treatment apparatus geometry.

System for analyzing the geometry of a radiation treatment apparatus, software and related methods

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.

System for monitoring the geometry of a radiation treatment apparatus, trackable assembly, program product, and related methods

A system to track a three-dimensional position and an orientation of a movable object and associated methods are provided. The system includes a tracker having an optically trackable body adapted to connect to the movable object. A plurality of optical indicators are connected or mounted to the optically trackable body to form a plurality of geometric figures. A plurality of obfuscating flanges optically separate the optical indicators from each other to prevent each of the optical indicators from becoming optically coincident with another optical indicator when viewed along a preselected viewing path. The system also includes an apparatus to track the tracker having an optical detector to simultaneously detect the three-dimensional position of at least three of the plurality of optical indicators and a determiner to determine the three-dimensional position and orientation of the optically trackable body from the position of the optical indicators.
