20100103804 | SYSTEM AND METHOD FOR PROCESSING OF IMAGE DATA IN THE MEDICAL FIELD - An image processing system in the medical field is provided. The system for processing image data includes at lest two graphics processors, at least one renderer module for rendering image data and at least one reconstruction module for volume reconstruction. In a first operating mode of the system in which at least one reconstruction module is inactive, the instructions of at least one renderer module is able to be executed by at least two of the graphics processors. In a second operating mode of the system in which at least one reconstruction module is active, the instructions of at least one renderer module and the instructions of at least one reconstruction module is able to be executed separately on different graphics processors of the said graphics processors. During operation in one of the two operating modes, a switch can be made to the other operating mode in each case. | 04-29-2010 |
20100246778 | Method for Calibrating the Position of a Laser Fan Beam Relative to the Projection Geometry of an X-Ray Device and X-Ray Device - For detecting the relative location of a laser or laser fan beam relative to the x-ray geometry of an x-ray device, a method for calibrating the position of the laser fan beam generated by a laser in relation to the projection geometry of the x-ray device is proposed. The x-ray device comprises an x-ray imaging system featuring an x-ray source and an x-ray detector. The x-ray source, the x-ray detector, the laser, and an imaging facility are arranged on a support. An optical x-ray calibration phantom is used for the calibration. The position of the imaging facility relative to the projection geometry is determined. The position of the laser fan beam relative to the imaging facility is determined. The position of the laser fan beam relative to the projection geometry is reconstructed. | 09-30-2010 |
20110072397 | Image Data and Annotation Processing System - A system automatically detects objects in an image and automatically displays a chosen object if the object is not currently visible in real time. An image data processing system automatically displays potentially hidden features in 3D (three dimensional) medical image data. A repository includes a 3D (three dimensional) image dataset representing an anatomical volume of interest. An image data processor processes the dataset retrieved from the repository by, (a) automatically detecting if a first object is obscured by a second object in the 3D image dataset, (b) automatically determining if the first object is visible by rotating the anatomical volume of interest and (c) rotating the anatomical volume of interest until the first object is visible in response to a command. A display processor initiates display of the rotated anatomical volume of interest. | 03-24-2011 |
20110201925 | Method and Apparatus for Determining the Vascularity of an Object Located in a Body - A method for determining a vascularity of an object located in a body is proposed. A multidimensional volume image of a target area of the body including the object is acquired. The object is segmented in the volume image. An expanded volume of the object is calculated by expanding structure edges of a volume of the object in the volume image with a predetermined size. The volume of the object is subtracted from the expanded volume of the object for determining an immediate vicinity of the object. A further object in the volume image having a determined minimum volume in the immediate vicinity of the object is segmented. A number of voxels of the further object is compared with a total number of voxels in the immediate vicinity of the object for determining the vascularity of the object. | 08-18-2011 |
20120014573 | Method and system for indicating a feeding vessel of a malformation in a medical image - A method and a system for indicating a feeding vessel of a malformation in a medical image are provided. The method first displays the medical image of the malformation and its surrounding vessels. This enables a manual selects a portion of the displayed medical image with reference to the tumor. The feeding vessel of the tumor is segmented and finally indicated in the medical image based on said manual selection. | 01-19-2012 |
20120014574 | Method for Determining Properties of a Vessel in a Medical Image - A method and a system for determining properties of a vessel in a medical image are provided. The method involves displaying the medical image including the vessel. The displayed vessel is segmented and indicated in the medical image. For an indicated vessel, a maximum curvature along a length of the vessel is determined as the property of the vessel. Another vessel parameter which can be determined is the smallest diameter along the length of the vessel. | 01-19-2012 |
20120014577 | Method and System for Indicating a Feeding Vessel of a Malformation - A method for indicating a feeding vessel of a malformation is presented. The method includes accessing a medical image with the malformation and segmenting the malformation in the medical image. Further, the method includes detecting the feeding vessel of the malformation and acquiring a live image, thereafter the method involves displaying the live image overlaid with the medical image as a displayed image and indicating the feeding vessel in the displayed image. | 01-19-2012 |
20120283556 | Method for assisting optimum positioning of an occlusion site in a blood vessel in a tumor embolization - A method for assisting optimum positioning of an occlusion site in a blood vessel in a tumor embolization is provided. Tumors are cut off from the blood supply by the embolization which is an artificial occlusion of blood vessels. The vessels around the tumor and at the same time the planned site for occlusion are firstly determined. A path from the access to the vessels can be determined based on image recognition, and with the aid of this path the site for occlusion can then be optimally determined. A computer system assists the doctor carrying out the treatment by a suitable display. | 11-08-2012 |
20130038629 | METHOD AND DEVICE FOR VISUALIZING THE REGISTRATION QUALITY OF MEDICAL IMAGE DATASETS - A method for visualizing a registration quality of medical image datasets is provided. A reference image and an object image are acquired and registered with each other to form a merged image by a registration method having a non-elastic and an elastic registration method section. A deformation field is determined having displacement vectors from image points of the object image to image points of the reference image which are conditioned by the elastic registration method section. One region of the merged image is overlayed with an overlay into which parameters of the deformation field are fed. The region of the merged image and the overlaid overlay is visualized. | 02-14-2013 |
