20080304615 | Method For Fleixble 3Dra-Ct Fusion - A system and method for combined processing and displaying of two data sets, originating from two different radiological methods, capable of making interim results, yielded by an operation on one of the data sets, available for further processing of the other data set. Different imaging capabilities of the employed radiological methods promote predestine the data acquired using a particular method for a particular task, e.g. the segmentation of a given type of tissue. When the combined data of both methods is displayed, clinical users benefit from the complementary information. Care has to be taken, that only relevant information is presented to the user, as to avoid irrelevant data obscuring any data of interest. Therefore, the data to be displayed is filtered based on content, e.g. the type of tissue, and on location. The invention is particularly useful with computer tomography and three-dimensional rotational angiography. | 12-11-2008 |
20090148009 | IMAGE PROCESSING SYSTEM AND METHOD FOR DISPLAYING IMAGES DURING INTERVENTIONAL PROCEDURES - To reduce the contrast fluid and X-ray load on patients during interventional procedures, a real-time visualisation architecture is proposed to combine 2D live images with 3D reconstructed volume information. In general, 2D X-ray images arc recorded from below (Posterior Anterior) and presented head up (Anterior Posterior) by applying a mirroring operation on the image data. In order to ensure a correct alignment of the 2D live images within the reconstructed 3D volume, as is proposed to display the 3D information under the same inverse viewing angle as the 2D live images by applying a mirroring around the Y-axis to the 3D information and by presenting the 3D information in a reverse sorting order. Furthermore, transparent surface/volume rendering may be combined with silhouette rendering to maintain the contrast in the 2D information while preserving the 3D impression. | 06-11-2009 |

20120237105 | ABLATION TREATMENT PLANNING AND DEVICE - An ablation treatment planning and, optionally, guiding method usable for e.g. tumour tissue ablation with a cryoablation needle which cools down an adjacent tumour tissue to thereby generate an ablation volume is proposed. In order to be able to plan an ablation treatment, a 3D image data set of a region of interest may be acquired by e.g. X-ray imaging using e.g. a C-arm system. Then, 3D model data of the ablation volume are introduced into the 3D image data set for example by tagging image pixels using a stencil buffer and possibly by culling specific inside areas and/or outside areas of the ablation volume. Finally, a 2D image to be visualized to a physician and comprising a projection of the region of interest and the ablation volume is drawn wherein an MPR (multi planar reformatting) plane in which the 2D image is drawn is used as a clipping plane. With such graphical approach, an ablation volume having any arbitrary shape such as for example an ellipsoid shape may be visualized within a 3D image space by drawing 2D images in any desired MPR plane such that also oblique orientations of the ablation volume can be represented. In a subsequent guiding procedure, an ablation needle may be guided to a location and in an orientation as previously planned. | 09-20-2012 |
