摘要： The invention provides a system for investigating a tissue of a subject by way of diffuse reflectance spectroscopy, the tissue including a fluorescent agent adapted to absorb light in a first wavelength range and emit light in a second wavelength range, different to the first. The system includes a cannula having a distal end to be positioned adjacent the tissue and an internal cavity for providing a suction force to the tissue. The system further includes a light source adapted to generate light at the first wavelength range and a fiber optic element to be positioned adjacent the tissue. The fiber optic element is adapted to receive a light signal from the fluorescent agent, the light signal comprising light in the first and second wavelength ranges. The system further includes a processing system adapted to determine a concentration of the fluorescent agent in the tissue based on the light signal.

摘要： A system may generally comprise a tracking device, an ultrasound device and a processing unit. A position and orientation of the ultrasound device may be traceable by the tracking device. The processing unit may be configured (i) to receive 3D information of a region of interest in relation to a marker, with both the region of interest and the marker being located within a body, (ii) to determine the position of the marker relative to the ultrasound device based on an ultrasound image of the body including the marker, and (iii) to determine the position and orientation of the ultrasound device relative to the tracking device. The system may further comprise a visualization device and the processing unit may further be configured to generate a visualization of the region of interest in relation to an outer surface of the body.

摘要： 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.

摘要： The invention relates to a system (8) for assisting a user in placing a penetrating device in tissue like a pedicle screw (7) in a vertebra’s pedicle. The system generates a virtual view (20) from a penetrating device tip perspective within the tissue in the direction of a path (21) through a model of the tissue. The virtual view is generated based on tracking information indicating a pose of the penetrating device, the model and the path, wherein the virtual view is configured such that it indicates a direction in which the user should move the penetrating device while placing it in the tissue. For instance, it can show a virtual tunnel (801) which is arranged along the path. If a user like a surgeon is provided with such a virtual view, the user can position the penetrating device along the path with a significantly increased accuracy.

摘要： A system SY for determining a tissue type TY of a tissue region TR is provided in which the distal ends OFDE1 . . . n of at least three optical fibers define a plurality of intersecting optical paths IOP1 . . . k within the tissue region TR. A tissue signal Q1 . . . k indicative of a tissue type TY for the respective optical path IOP1 . . . k is generated from said spectral measurement data SMD corresponding to each of the plurality of intersecting optical paths IOP1 . . . k. Each tissue signal Q1 . . . k is compared with a reference threshold QRT for the tissue type, and with an average of the tissue signals QMA. At least a portion of the tissue region is identified as the tissue type TY if i) every tissue signal Q1 . . . k in the tissue region TR indicates that its corresponding tissue is not the tissue type TY in the comparison with the N reference threshold QRT and ii) at least one of the tissue signals Q1 . . . k in the tissue region TR lies between the average QMA of the tissue signals Q1 . . . k and the reference threshold QRT, and a difference Δ between the at least one tissue signal Q1 . . . k and the average QMA of the tissue signals Q1 . . . k exceeds a predetermined value ΔP.

摘要： The invention relates to an ultrasound device (1) insertable into a patient body (2) for in-situ ultrasound imaging. The device (1) comprises an ultrasound transducer device (4) having an imaging surface (5) for contacting tissue to be imaged and being attached to a support element (21). The support element (21) comprises a gripping member (21, 23) having a gripping surface configured for being at least temporarily affixed to the tissue, the gripping member (21) at least partly surrounding the imaging surface (5) of the ultrasound transducer device (4) and the gripping surface (23) being made from a deformable material. By means of the gripping member (21, 23), the device (1) can automatically be held at an imaging position. Further, the device (1) does not require an elongated shaft for manipulating the ultrasound module, which could interference with other surgical devices.
