摘要： A method and system for fully automatic segmentation the prostate in magnetic resonance (MR) image data is disclosed. Intensity normalization is performed on an MR image of a patient to adjust for global contrast changes between the MR image and other MR scans and to adjust for intensity variation within the MR image due to an endorectal coil used to acquire the MR image. An initial prostate segmentation in the MR image is obtained by aligning a learned statistical shape model of the prostate to the MR image using marginal space learning (MSL). The initial prostate segmentation is refined using one or more trained boundary classifiers.

摘要： Automatic prostate localization in T2-weighted MR images facilitate labor-intensive cancer imaging techniques. Methods and systems to accurately segment the prostate gland in MR images are provided and address large variations in prostate anatomy and disease, intensity inhomogeneities, and artifacts induced by endorectal coils. A center of the prostate is automatically detected with a boosted classifier trained on intensity based multi-level Gaussian Mixture Model Expectation Maximization (GMM-EM) segmentations of the raw MR images. A shape model is used in conjunction with Multi-Label Random Walker (MLRW) to constrain the seeding process within MLRW.

摘要： In a method for contrast agent-free magnetic resonance colonography, blood that flows into the bowel tissue is prepared automatically by radio-frequency pulses. Magnetic resonance data of the bowel are acquired while the prepared blood is located in the bowel, and a magnetic resonance image of the bowel is created from the magnetic resonance data. Bowel tissue regions and regions with bowel content are differentiated automatically on the basis of an increased contrast (caused by the preparation) between perfused tissue regions and regions of the gut lumen that are not perfused.

摘要： In a method for the implementation of a medical examination via the user interface of at least one imaging device, parameter values in a group of measurement parameters are determined, and are entered via an input device of the user interface. Spatially resolved image information are generated by the at least one imaging device depending on the group of measurement parameters, and the image information is stored on a storage medium. The image information are presented as a data symbol on a screen of the user interface. In order to present the parameters and dependencies to enable a more efficient work process, each measurement parameter of the group of measurement parameters is respectively presented on the screen in a measurement parameter cell of a matrix with multiple rows and multiple columns. The measurement parameters can be contained at least in part in multiple measurement parameter cells. The presentation size of the multiple columns of the matrix depends on their distance from the pointer symbol on the screen.
