Abstract:
1. A system for integrated guidance for positioning a biopsy device in a body, the system comprising: a tracking device for coarse guidance of the biopsy device to a biopsy location in the body; and an analyze device for fine guidance of the biopsy device to the biopsy location in the body, wherein the fine guidance is a final precise guidance to the biopsy location more precise than the coarse guidance being an initial guidance to the biopsy location, the analyze device comprising an optical detector configured to detect structures of tissues of the body for providing visible images of the structures, and a console configured to perform a spectroscopy to obtain spectral light distributions of the tissues, wherein the visible images from the optical detector include optically obtained image boundaries of the different tissues, wherein the console and the optical detector are connected to each other, wherein the analyze device is configured to provide information for discriminating different tissues including the optically obtained image boundaries of the different tissues of the body from each other based on the visible images of the structures of the tissues combined with the spectral light distributions of the tissues; a processor configured to combine the information for discriminating the different tissues including the optically obtained image boundaries of the different tissues obtained by the analyze device with non-invasive image-determined boundaries from an image of a non-invasive imaging device providing images of the structures to calculate a scale factor between the optically obtained image boundaries and the non-invasive image-determined boundaries, and using the scale factor to enlarge the non-invasive image-determined boundaries to fully overlap the optically obtained image boundaries to obtain new boundaries of a region of interest; and the biopsy device comprising an elongate element and a tip portion, wherein the biopsy device is configured to be traced by the tracking device, wherein the optical detector is integrated in the tip portion of the biopsy device.
