Abstract: For checking the positional accuracy, a method for automatically monitoring a position and/or an angle of inclination of a component of a medical mobile X-ray device using at least one inertial measurement unit is provided. The mobile X-ray device has a device trolley and an adjustable C-arm. The at least one inertial measurement unit is arranged on the mobile X-ray device. The method includes: acquiring at least one measured value of the inertial measurement unit; evaluating the at least one measured value of the inertial measurement unit with regard to a position and/or an angle of inclination of the component of the mobile X-ray device; comparing the evaluated position and/or the at least one evaluated angle of inclination with at least one specified value and determining deviations from the at least one specified value; and outputting an indication or a display when the deviation overshoots a threshold value.

Abstract: A method for automatically analyzing an aortic aneurysm includes providing a digitized 3-dimensional image volume of an aorta, determining which voxels in said image are likely to be lumen voxels, determining a distance of said lumen voxels from an aortic boundary, finding a centerline of the aorta in said image volume based on said lumen voxel distances, constructing a series of 2-dimensional multiplanar reformatted (MFR) image planes orthogonal to this centerline, segmenting aortic cross sections in each said MPR image plane wherein an aortic wall is located in each MPR image, and constructing from said aortic wall locations a 3D model of the aorta.

Abstract: A system and method for tracking and classifying the left ventricle of the heart using cine-delayed enhancement magnetic resonance (Cine-DEMR) are provided. The method for tracking the left ventricle comprises: delineating myocardial borders of the left ventricle in an image of a first phase of a cardiac cycle of the heart; registering the image of the first phase with an image of a second phase of the cardiac cycle; copying the myocardial borders from the first phase onto the second phase; fitting the myocardial borders of the first phase to myocardial borders of the second phase; and refining the myocardial borders of the second phase.

Abstract: A method of magnetic resonance imaging of anatomy that is subject to a movement cycle (e.g., the heart during a cardiac cycle), comprising: administering a magnetic resonance contrast agent; waiting a period of time until the contrast agent is effective to cause selected portions of the anatomy (e.g.

Abstract: A method and device for image processing to determine image characteristics includes operations of segmenting of first images to create segmentation contours corresponding to the first images; and registering the segmented first images to second images. Further, operations of transferring the segmentation contours from the first images to second images; and fitting the transferred segmentation contours in the second images are performed.
