摘要： The invention relates to a magnetic resonance imaging system (100) comprising a main magnet (104), a magnetic field gradient system with antenna elements (114), a radio-frequency system, a memory (136) storing machine executable instructions comprising a first set of machine executable instructions (150) for operating the magnetic resonance imaging system (100) in a pre-data-acquisition-mode in which data acquisition by the antenna elements (114) is switched off, and a processor (130) for controlling the magnetic resonance imaging system (100). An execution of the first set of machine executable instructions (150) causes the processor (130) to control the magnetic resonance imaging system (100) to generate in the pre-data-acquisition-mode acoustic sound using the magnetic field gradient system. The generation of the acoustic sound comprises generating an alternating gradient magnetic field by the magnetic field gradient system.

摘要： A synergized pulsing-imaging network is described. A method of optimizing a magnetic resonance imaging (MRI) system includes optimizing, by a synergized pulsing-imaging network (SPIN) circuitry, a pulse sequence based, at least in part, on a loss function associated with a reconstruction network. The method further includes optimizing, by the SPIN circuitry, the reconstruction network based, at least in part, on intermediate raw MRI data and based, at least in part, on a ground truth MRI image data. The intermediate raw MRI data is determined based, at least In part on the pulse sequence.

摘要： The invention relates to a method of Dixon-type MR imaging. The method comprises the steps of: subjecting the object (10) to an imaging sequence (31) comprising a series of refocusing RF pulses, wherein two echo signals are generated in each time interval between two consecutive refocusing RF pulses, acquiring the echo signals from the object (10) using a bipolar pair of readout magnetic field gradients, wherein the two readout magnetic field gradients have different strengths such that the corresponding two echo signals are acquired at different receive bandwidths, and reconstructing a MR image from the acquired echo signals, whereby signal contributions from water protons and fat protons are separated. Moreover the invention relates to a MR device (1) and to a computer program to be run on a MR device (1).
