Abstract: The present invention relates to medical instrument tracking. In order to facilitate tracking a medical instrument, a system (100) is provided for tracking a medical instrument. The system comprises an instrument marker (14), a tracking arrangement (16), and a processing unit (18). The instrument marker is attached to the medical instrument on a marker position (20). The tracking system is configured to detect line segments (22) in the 5 field of interest and to detect the attached instrument marker. The processing unit is configured to identify a line segment (24) on which the attached instrument marker is detected as the medical instrument, and to determine an offset (26) between a position of a medical instrument tip (28) and the marker (14) by touching a reference marker (34) on the subject with the medical instrument (10).

Abstract: The present invention relates to positioning of an X-ray imaging system. In order to provide an improved relative positioning of the X-ray imaging system for spine interventions, a device (10) for positioning of an X-ray imaging system is provided. The device comprises a data storage unit (12), a processing unit (14) and an output unit (16). The data storage unit is configured to store and provide 3D image data (18) of a spine region of interest of a subject comprising a part of a spine structure, the spine structure comprising at least one vertebra. The processing unit is configured to select at least one vertebra of the spine structure as target vertebra; to segment at least the target vertebra in the 3D image data; wherein the segmentation comprises identifying at least one anatomic feature of the target vertebra; to define a position of a predetermined reference line based on a spatial arrangement of the at least one anatomic feature; and to determine a target viewing direction of an X-ray imaging system based on the reference line. The output unit is configured to provide the target viewing direction for an X-ray imaging system.

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: Various embodiments of the present disclosure include a C-arm registration system employing a controller (70) for registering a C-arm (60) to a X-ray ring marker (20). The X-ray ring marker (20) includes a coaxial construction of a chirp ring (40) and a centric ring (50) on an annular base (30). In operation, the controller (70) acquires a baseline X-ray image illustrative of the X-ray ring marker (20) within a baseline X-ray projection by the C-arm (60) at a baseline imaging pose, derives baseline position parameters of the X-ray ring marker (20) within the baseline X-ray projection as a function of an illustration of the centric ring (50) within the baseline X-ray image, and derives a baseline twist parameter of the X-ray ring marker (20) within the baseline X-ray projection as a function of the baseline position parameters and of an illustration of the chirp ring (40) within the baseline X-ray image.
