Abstract: A medical apparatus (1100) comprising a magnetic resonance imaging system and an interventional device (300) comprising a shaft (302, 1014, 1120). The medical apparatus further comprises a toroidal magnetic resonance fiducial marker (306, 600, 800, 900, 1000, 1122) attached to the shaft. The shaft passes through a center point (610, 810, 908, 1006) of the fiducial marker. The medical apparatus further comprises machine executable instructions (1150, 1152, 1154, 1156, 1158) for execution by a processor. The instructions cause the processor to acquire (100, 200) magnetic resonance data, to reconstruct (102, 202) a magnetic resonance image (1142), and to receive (104, 204) the selection of a target volume (1118, 1144, 1168). The instructions further cause the processor to repeatedly: acquire (106, 206) magnetic resonance location data (1146) from the fiducial marker and render (108, 212) a view (1148, 1162) indicating the position of the shaft relative to the target zone.

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.

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: A device for positioning of an X-ray imaging system. The device comprises a processor configured to obtain 3D image data of a spine region of interest of a subject comprising a spine structure. The processor is further configured to select at least one vertebra of the spine structure as target vertebra; segment the target vertebra in the 3D image data including identifying at least one anatomic feature of the target vertebra; define a position of a predetermined reference line based on a spatial arrangement of the at least one anatomic feature; determine a target viewing direction of the X-ray imaging system based on the predetermined reference line; and provide the target viewing direction for the X-ray imaging system.

Abstract: The present invention relates to guidance during a medical intervention. In order to provide an improved navigation support with a facilitated setup, a system (10) for navigation support is provided. An image data input (12) receives a plurality of acquired 2D X-ray images of a subject's body from different angles. A set of markers, which are visible in X-ray images and which are detectable by a navigation system, is assigned to the subject. A marker detecting arrangement (16) is provided that detects a current spatial location of the markers assigned to the subject. A data processor (14) reconstructs a 3D volume of the subject based on the plurality of 2D X-ray images. At least a part of the markers is arranged outside the volume covered by the reconstructed 3D volume of the subject, while the markers are visible in the 2D X-ray images. The data processor (14) identifies the markers in the 2D X-ray images based on image data of the plurality of 2D X-ray images outside the 3D volume and determines a spatial location of the markers in relation to the 3D volume of the subject. The data processor (14) also registers the reconstructed 3D volume of the subject to a current spatial position of the subject based on the detected current spatial location of the markers and the determined spatial location of the markers in relation to the 3D volume of the subject. An output interface (18) provides the registered reconstructed 3D volume for navigation.
