| 20080278489 | Image Processing System and Method for Silhouette Rendering and Display of Images During Interventional Procedures - A medical viewing system in which 3DRA images of a body volume are acquired and two dimensional live image data is acquired within the body volume during an intervention. Direct volume silhouette rendering is performed in respect of the 3D image so as to generate a silhouette rendering of the 3D image comprised of values proportional to the translucency of voxels of the 3D image data, and the live sequence of 2D images ( | 11-13-2008 |
| 20100172541 | TARGETING METHOD, TARGETING DEVICE, COMPUTER READABLE MEDIUM AND PROGRAM ELEMENT - According to an exemplary embodiment a targeting method for targeting a first object from an entry point to a target point in an object ( | 07-08-2010 |
| 20100194750 | VISUALIZATION OF ANATOMICAL DATA - The invention relates to an apparatus and a method for examination and visualization of an object of interest. The apparatus comprises a display, an input device, and a calculation unit, wherein the calculation unit is adapted for performing the following steps: acquiring a first data set; acquiring a second data set; fusing the first and second data sets; determining image parameters entered by means of the input device, related to at least one of an image plane, an angle of view, a contrast and a transparency; rendering an image on the basis of the data sets and the determined parameters, resulting in a combined image with selected areas of transparency and selected areas of visible contrast information, wherein the image is visualized on the display. Provided with such images, the physician will be able to easily identify structures of interest and to localize said structures in the anatomical environment. Further, the physician will be able to monitor instruments which the physician uses in an interventional procedure. | 08-05-2010 |
| 20100215213 | TARGETING METHOD, TARGETING DEVICE, COMPUTER READABLE MEDIUM AND PROGRAM ELEMENT - This invention will introduce a fast and effective target approach planning method preferably for needle guided percutaneous interventions using a rotational X-ray device. According to an exemplary embodiment A targeting method for targeting a first object in an object under examination is provided, wherein the method comprises selecting a first two-dimensional image of an three-dimensional data volume representing the object under examination, determining a target point in the first two-dimensional image, displaying an image of the three-dimensional data volume with the selected target point. Furthermore, the method comprises positioning the said image of the three-dimensional data volume by scrolling and/or rotating such that a suitable path of approach crossing the target point has a first direction parallel to an actual viewing direction of the said image of the three-dimensional data volume and generating a second two-dimensional image out of the three-dimensional data volume, wherein a normal of the plane of the second two-dimensional image is oriented parallel to the first direction and crosses the target point. | 08-26-2010 |
| 20100296623 | VISUALIZATION OF 3D IMAGES IN COMBINATION WITH 2D PROJECTION IMAGES - It is described an improved visualization of an object under examination ( | 11-25-2010 |

| 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 |
| 20100061603 | SPATIALLY VARYING 2D IMAGE PROCESSING BASED ON 3D IMAGE DATA - It is described a 2D image processing of an object under examination in particular for enhancing the visualization of an image composition between the 2D image and a 3D image. Thereby, (a) a first dataset representing a 3D image of the object is acquired, (b) a second dataset representing the 2D image of the object is acquired, (c) the first dataset and the second dataset are registered and (d) the 2D image is processed. Thereby, based on image information of the 3D image, within the 2D image processing there is at least identified a first region ( | 03-11-2010 |
