Abstract

This application describes a medical device (230) for obtaining optical tissue properties of a target material. The medical device (230) comprises an elongated body (231) having a longitudinal axis (232) and an optical fiber being integrated within the elongated body (231). The optical fiber has a second fiber end (242, 242a, 242b), which is arranged at a side wall (233) of the elongated body (231) and which provides a lateral field of view with respect to the longitudinal axis (232). According to an embodiment many optical fibers are integrated each having an optical outlet (242, 242a, 242b) around the elongated body (231). Using the outlets (242, 242a, 242b) to do diffuse optical tomography and also use optical fibers to do an optical inspection, one can get information on the presence of tumors in a volume around the medical device (230) and a tissue characterization in the vicinity of the medical device (230). Thereby, an optical biopsy may be carried out, wherein no real tissue is removed. According to another embodiment an optical detection system is integrated into a real biopsy needle (330) allowing inspection and taking real biopsy simultaneously.

Description

technical field [0001] The invention relates to the field of medical tissue inspection. In particular, the invention relates to medical devices, such as needles, for acquiring optical tissue properties of the human or animal body. The medical device insertable into the tissue to be probed comprises at least one optical fiber for directing illumination light to the tissue and for receiving measurement light interacting with the tissue. The invention also relates to a medical apparatus and a method for acquiring optical tissue properties of a human or animal body. The medical devices and methods all benefit from the medical device. Background technique [0002] To correct the diagnosis of various cancerous diseases, biopsies are used. This can be achieved either through the lumen of an endoscope or through a needle biopsy. A biopsy may be taken from the prostate, for example, through the rectum. To find the correct location for the biopsy, various imaging modalities are u...
