ABSTRACT:
A non-diagnostic, stereoscopic x-ray tracking apparatus and method for tracking moving objects in the context of radiotherapy and radiosurgery includes using two x-ray tubes to alternately and repeatedly record x-ray images of an object along two different viewing lines through the target area of an irradiating apparatus. The viewing lines intersect at a known angle, wherein an extrapolated object trajectory is ascertained by determining surfaces and intersecting points. Further, a minimum transversal from the object trajectory onto a current viewing line is ascertained, wherein the three-dimensional position of the tracked object is approximated at the point at which the object trajectory meets the viewing line.
