<p>This invention relates to internal markers (152) attached to the target organ (151) being imaged by a stereotaxic x-ray device. The internal markers (152) on the target organ (151) may be imaged by a first x-ray source (160), and a second x-ray source (162) which are positioned at some predetermined angle with respect to each other similar to the diagnostic x-ray beams. The x-ray sources may generate a first, a second diagnostic x-ray beam (164, 166) that pass through a target organ (151) near the internal markers (152) that are received by a first, a second x-ray receiver (168, 170), respectively, which receive the x-ray beams, and generate an electrical signal corresponding to the received x-rays. The stereotaxic x-ray device permits the precise location of the internal markers (152) to be determined by analyzing the images generated.</p> |
