Abstract
Method and apparatus for storing and moving an x-ray detector assembly in and out of the field of radiation produced by a radiation therapy simulator source while remaining affixed to the gantry of the simulator and retaining the functional attributes of a standard radiation therapy simulator cassette holder. When mounted to the simulator, the apparatus of the present invention has the ability to position an x-ray cassette in a fixed position relative to the radiation source, allow for the use of an image intensifier tube by being effectively radiolucent over the tube, and incorporating a mechanism which is capable of absorbing a degree of movement independent of the gantry while simultaneously activating a switch mechanism which can be used to stop gantry rotation, thereby preventing damage to the device or that which it contacts.
