摘要： A gantry has an X-ray detecting part and an X-ray generating part with at least one X-ray source. The X-ray generating part and the X-ray detecting part are rotatable around a scan region, wherein the X-ray generating part is configured to generate X-rays via the at least one X-ray source and to send the X-rays into any part of the scan region. The X-ray detecting part is configured to detect X-rays generated by the X-ray generating part, wherein the X-ray generating part is configured to dynamically adjust the generated X-rays such that at multiple rotational positions X-rays are selectively sent into a partial region and/or such that X-rays of different intensity are sent into different partial regions.

摘要： A magnetic resonance tomography unit for localizing metallic objects and an operating method are provided. In one act of the method, an excitation pulse is used to excite nuclear spins in a region surrounding a compact metallic object. Magnetic resonance data is acquired with samplings along a plurality of trajectories, where the samplings take place using a bSSFP sequence, and the nuclear spins are dephased by a gradient. A position of a geometric focal point of the compact metallic object is ascertained based on a position of a visual focal point of acquired artifacts.

摘要： A method for operating an X-ray imaging system includes outputting first X-ray beams onto an X-ray detector by an X-ray source for acquisition of a first X-ray capture of an object under examination. The object under examination is arranged between the X-ray source and the X-ray detector and is passed through by the first X-ray beams. The X-ray detector acquires an entry dose of the first X-ray beams after passage through the object under examination. A parameter value of at least one parameter for output of second X-ray beams by the X-ray source for acquisition of a second X-ray capture of the object under examination is ascertained by a control system. The parameter value is ascertained by the control system according to a specified ascertainment method as a function of a foreground substance of a foreground object, a background substance of a background object, and the entry dose.

摘要： A method for assigning a spatial orientation to a movement signal of a movement of an examination object of a magnetic resonance examination, a magnetic resonance apparatus and a computer program product. According to the method, a first movement signal is captured by means of a first movement capture method. During the capture of the first movement signal, at least one further movement signal is captured by means of at least one further movement capture method. A spatial orientation is assigned to at least one component of the first movement signal by comparing the first movement signal with the at least one further movement signal.

摘要： A magnetic resonance (MR) image may be created from MR data by receiving the MR data, applying a transform to the MR data, where a result of the applying is an image space representation of the MR data, determining a wrapped phase map of the image space representation of the MR data, obtaining an unwrapped phase map based on the wrapped phase map, scaling the unwrapped phase map into a B0 field map, reconstructing the MR image based on the MR data, correcting the MR image based on the B0 field map, and outputting the MR image. The scaling may be free of accounting for effects on the MR data by artifact sources secondary to B0 field inhomogeneities.
