The present invention relates to an ultrasound imaging system (100) for producing spatially compounded 3D ultrasound image data, comprising: —an ultrasound acquisition unit (16) for acquiring a plurality of 3D ultrasound image data having different but at least partially overlapping field of views, —a tracking unit (62) adapted to determine a relative spatial position of each of 5 the plurality of 3D ultrasound image data with respect to each other, and —a stitching unit (64) adapted to compound the plurality of 3D ultrasound image data by stitching them to each other in order to generate compounded 3D ultrasound image data, wherein the stitching unit (64) is adapted to calculate a stitching order of the plurality of 3D ultrasound image data based on the determined relative spatial position of the 3D 10 ultrasound image data by minimizing an overlapping area of the different field of views of the plurality of 3D ultrasound image data, and wherein stitching unit (64) is adapted to stitch the plurality of 3D ultrasound image data according to said stitching order.
Abstract:
The invention relates to a delivery assistance device for assisting in a brachytherapy procedure. The invention provides for an output of an optimized treatment plan, taking into considering the portions of the procedure already carried out. The invention provides for an update of the sequence and the dosing after, for example, each needle insertion. The sequence of the treatment plan is determined such that, for example, steps of the procedure in which an error may have a larger impact, which needs to be corrected by modifying later steps, are provided earlier than steps in which an error is less likely and/or may have a lesser impact.
Abstract:
The invention relates to a system for applying radiation to a target region within a subject. An introduction element (12) like a brachytherapy catheter is inserted into the subject and a radiation source (10) is moved within the introduction element such that it is located within or close to the target region. The target region is heated, wherein the movement of the radiation source within the introduction element is controlled depending on the temperature along the introduction element. The susceptibility of the subject for the radiation emitted by the radiation source at a respective location along the length of the introduction element can depend on the temperature at the respective location such that by controlling the movement of the radiation source depending on the temperature along the length of the introduction element the application of the radiation can be optimized.

Abstract:
A registration apparatus registers an elongated introduction element (18), like a catheter or a needle, during an interventional procedure, for instance, a brachytherapy or a biopsy. A guide element (13) includes at least one opening which guides the introduction element when being introduced into a living being (2) through the opening. A temperature profile generation element (14) associated with the opening generates a characteristic temperature profile at the opening for being transferred to the introduction element when being present in the opening. A temperature determination unit (15) determines a temperature along the introduction element, and a registration unit (16) registers the introduction element. The registering includes identifying the transferred characteristic temperature profile on the introduction element based on the determined temperature. This allows the registration unit to register the introduction element during the introduction process in a simple and efficient manner.
