Abstract: A method for determining a patient movement during a medical imaging measurement with an imaging apparatus, a computer-implemented method for providing trained functions, an imaging apparatus, and a computer program product are provided. The method for determining the patient movement provides that reference image data of a body region, such as a head region, of a patient is acquired and the patient movement is determined with the aid of the reference image data.

Abstract: The disclosure describes a magnet system for a magnetic resonance imaging system comprising a basic field magnet and a gradient system, wherein coils of the gradient system are positioned outside the area of a predefined basic magnetic field (B0) of the basic field magnet.

Abstract: The invention concerns a method for reconstructing medical image data which has access to free capacities of at least two computers and manages the use thereof for the purposes of the reconstruction. The method is a particularly reliable alternative to the reconstruction of medical image data based on algorithms that would require a working memory of above-average size.

Abstract: A medical imaging device having at least one lenticular image, a lenticular image for use in a medical imaging device and the use or positioning of a lenticular image in a medical imaging device is provided. In order to increase patient comfort during an examination, the medical imaging device comprises a hollow cylindrical opening in which a patient can be positioned for the recording of medical image data from the patient, wherein at least one lenticular image is arranged on an inner wall of the hollow cylindrical opening.

Abstract: In a magnetic resonance method and apparatus for generation of an angiographic image of a vascular system of a patient, a first data set of k-space data of the region to be examined is acquired using a contrast agent-free magnetic resonance angiography technique, a second data set of k-space data of the region to be examined is acquired using a contrast agent-assisted magnetic resonance angiography technique, and an angiographic image of the region to be examined is produced using both the first measurement data of the first data set and the second measurement data of the second data set.

Abstract: In a method and apparatus for generation of an image in contrast agent-supported magnetic resonance angiography, a first data set is generated during an arterial phase of a distribution of a contrast agent in a vessel system by scanning of a first central k-space region, a second data set is generated during an equilibrium phase of the distribution of the contrast agent in the vessel system by scanning a peripheral k-space region while omitting scanning of a second central region, and the image is generated by merging the first data set and the second data set.

Abstract: In a magnetic resonance imaging method and apparatus and computer program product, spatial scanning of a block-shaped volume of a patient is undertaken by applying a phase-coding gradient in a slice selection direction, as well as by applying a frequency-coding gradient in a plane vertical to the direction of the phase-coding gradient. The body is uniformly and continuously moved by uniformly and continuously moving a table on which the body is situated until the block-shaped volume moves uniformly through the homogeneity volume of the magnetic resonance apparatus. The gradient fields are simultaneously uniformly continuously shifted in conformity with the motion of the table, so that the block-shaped volume being scanned does not move in relation to the table, and thus does not move in relation to the patient, until the block-shaped volume proceeds through the entirety of the homogeneity volume, and scanning is completed.
