Abstract: A system and method of assisting a treatment procedure is provided, the method comprising the steps of determining a 3-D intervention vector in relation to an inner body structure of a body of interest based on a 3-D x-ray image, determining a 3-D position of an entry point on an outer surface of the body of interest based on the intervention vector, comparing the position and/or orientation of the inner body structure in the 3-D x-ray image with the position and/or orientation of the inner body structure in an additional 2-D x-ray image being generated transverse to the intervention vector, correcting the 3-D position of the entry point on the outer surface of the body of interest based on a deviation detected in the comparing step.

Abstract: The invention relates a system for implanting an implantable device in bone tissue, a processing unit for such system, a method of implanting an implantable device and a method of providing information for an implanting of an implantable device. In view of the finding that a fat content in cancellous bone is higher than a fat content in compact bone, the lipids fraction, which can be determined by optical means, e.g. spectroscopy, can be used to determine correct screw placement in healthy bone.

Abstract: The present invention relates to an intravascular device (10). The device comprises an elongate member (20), an optical fiber (30), and at least one optical interaction element (40). At least a part of the elongate member is configured to be inserted into a part of a vascular system of a patient. At least a part of the optical fiber is located within the elongate member. The optical fiber is configured to transmit optical wavelength radiation. The intravascular device is configured to emit optical wavelength radiation out of the elongate member in at least two optical radiation beams for being scattered and/or reflected by a portion of the vascular system. The emission of the at least two optical radiation beams comprises interaction of the transmitted optical wavelength radiation with the at least one optical interaction element. The intravascular device is configured to collect at least some of the scattered and/or reflected optical wavelength radiation and couple the at least some of the scattered and/or reflected optical wavelength radiation into the optical fiber comprising utilization of the at least one optical interaction element.

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.

Abstract: A system is suggested comprising an optical sensing means and a processing unit. The optical sensing means may include an optical guide with a distal end, wherein the optical guide may be configured to be arranged in a device to be inserted into tissue in a region of interest. The processing unit may be configured to receive information of a region of interest including different tissue types as well as of a path through the tissues, to determine a sequence of tissue types along the path, to determine a tissue type at the distal end of the optical guide based on information received from the optical sensing means, to compare the determined tissue type with the tissue types on the path, to determine possible positions of the distal end of the optical guide on the path based on the comparison of tissue types, and to generate a signal indicative for the possible positions.

Abstract: An orthopedic pin (100) for optically analyzing a bone region (110) includes an elongate shaft (101) and at least one optical fiber (105) The elongate shaft has a circular outer cross section with a first diameter (D1), a distal end (102) for insertion into bone, a proximal end (103), and an optical connector portion (104) disposed towards the proximal end (103). The at least one optical fiber (105) extends within the elongate shaft (101) between the optical connector portion (104), and the distal end (102) for transmitting optical radiation between the optical connector portion (104) and the bone region (110) when the distal end (102) is inserted into the bone region (110). The optical connector portion (104) comprises a reduced-diameter portion (106). The reduced-diameter portion (106) extends along at least a portion of the elongate shaft (101), and has an outer cross section comprising a width (Drd) perpendicularly with respect to the elongate shaft (101). The width (Drd) is less than the first diameter (D1).

Abstract: The application relates to the problem of navigating a surgical instrument (at 301, 311) towards a region-of-interest (at 312) in endoscopic surgery when an image (300) provided by the endoscope is obscured at least partly by obscuring matter (at 303), wherein the obscuring matter is a leaking body fluid, debris or smoke caused by ablation. To address this problem, a computer-implemented method is proposed, wherein, upon detecting that the image from the endoscope is at least partly obscured, a second image is determined based on a sequence of historic images and based on the current position and orientation of the endoscope. Furthermore, a virtual image (310) is generated based on the determined second image.
