Digital radiography for target point evaluation in stereotactic neurosurgery.
Today, the usual target point evaluation during stereotactic operations using planar X-ray films can be supplemented by digital video storage. The picture-delivering system is a digital X-ray video chain which replaces the X-ray film. Evaluation of target point coordinates as well as parameters of electrode approach and positioning are determined by a microcomputer. Such an inexpensive system is described.
