摘要： The invention relates to a system for assisting a user in positioning a thermal ablation device (1) on the basis of a planned ablation position. The system comprises an evaluation unit (6) adapted to (i) compute an optimized thermal dose distribution deliverable to the treatment region by means of the device (1) operating at a current position thereof, (ii) determine a path for steering the device (1) from the current position to the planned position and to assign a cost to the determined path, the cost quantifying estimated detrimental effects of steering the device (1) along the computed path, and (iii) present information about the optimized thermal dose distribution and about the cost assigned to the computed path to the user.

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.
