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

1-31. (canceled)
A system for integrated guidance for positioning a biopsy device in a body, the system being configured for deducing tumor boundaries and comprising:
- an X-ray imaging device configured to provide coarse guidance, providing images of body structures, the X-ray imaging device providing X-ray information giving an estimate of a shape of a tumor,
- an analyze device configured to provide fine guidance, comprising an optical element and providing one-dimensional information of the tumor boundary along a needle trajectory by discriminating tissue of the body, wherein the information provided by the analyze device is registered in the image provided by the imaging device, and a biopsy needle being an elongate element with a tip portion,
- wherein the biopsy needle is adapted to be visualized by the X-ray imaging device, and
- wherein the optical element is in the tip portion of the biopsy needle,
- wherein the system is further configured to calculate a new estimate of 3D tumor size by combining the X-ray shape of the tumor with the one dimensional information of the analyze device.
