BIOPSY GUIDANCE BY IMAGE-BASED X-RAY GUIDANCE SYSTEM AND PHOTONIC NEEDLE

摘要

A system for providing integrated guidance for positioning a needle in a body has two levels of guidance: a coarse guidance and a fine guidance. The system comprises a non-invasive imaging system for obtaining an image of the biopsy device in the body, for providing the coarse guidance. Furthermore, the system comprises an optical element mounted on the needle for obtaining optical information discriminating tissue in the body, for providing the fine guidance.
