摘要： A database contains variants of protocols for the operation of magnetic resonance tomographs as well as different types of magnetic resonance tomographs. Each variant contains parameter values and is associated with one of the types. In a training phase, relationships are determined between the parameters among one another and/or between the parameters and the associated types and are stored as patterns in a knowledge base. A protocol plan for the operation of a new magnetic resonance tomograph is created later in an application phase using the determined pattern. The method offers the advantage that the efficiency and quality of the automatic conversion of the protocols is improved. The improved quality of the protocol plan reduces operating time and costs for a manual post-processing of the protocols. Furthermore, a higher consistency of the protocols among one another is achieved both between product families and between individual configurations.

摘要： In a method for acquiring dynamically varying magnetic resonance signals, a respiration cycle of a patient is monitored in a learning phase. Acquisition of varying signals ensues with the highest possible temporal resolution in an initial phase with a breath-hold by the patient. Slowly varying signals are subsequently acquired with lower temporal resolution in a movement phase and with free respiration of the patient. The signal acquisitions are initiated by a pre-established trigger condition.

摘要： In a method for implementation of a magnetic resonance examination of a patient with an imaging medical magnetic resonance apparatus with a movable patient bed, for of an examination volume of the patient that is larger than an acquisition volume of the magnetic resonance apparatus, anatomical patient information and second technical information for setting the magnetic resonance apparatus are acquired dependent on the position of the patient bed from magnetic resonance signals acquired in a low-resolution calibration measurement (scan). A first group of measurement protocol parameters is generated from the patient information and a second group of measurement protocol parameters is generated from the technical information, to generate a measurement protocol for a subsequent high-resolution magnetic resonance examination.

摘要： In a processing system for an MRT apparatus, a user interface as presented that permits an operator to undertake a graphical measurement planning based on already-recorded, corrected MRT overview images, the correction having been carried out by the processing system on the basis of stored data accessible by the processing system relating to non-linearities of the gradient system of the MRT apparatus being used. The processor system, in the user interface, automatically graphically demarcates the area of the corrected MRT overview image in which a positioning of additional slices to be measured will lead to a deviation of the desired slices, from the actual slices in a subsequent scan from the ear of the corrected MRT overview image in which a positioning of additional slices to be measured will not lead to such a deviation of the desired slices.

摘要： In a method for image guided prostate cancer needle biopsy, a first registration is performed to match a first image of a prostate to a second image of the prostate. Third images of the prostate are acquired and compounded into a three-dimensional (3D) image. The prostate in the compounded 3D image is segmented to show its border. A second registration and then a third registration different from the second registration is performed on distance maps generated from the prostate borders of the first image and the compounded 3D image, wherein the first and second registrations are based on a biomechanical property of the prostate. A region of interest in the first image is mapped to the compounded 3D image or a fourth image of the prostate acquired with the second modality.
