Abstract: A magnetic resonance (MR) system configured to acquire MR data from a subject using a set of waveform and pulse sequence commands to prepare a first state of vibration of the one or more hardware elements and/or the subject. Preparing includes generating the vibration matching gradient inducing the first vibrations of the one or more hardware elements and/or the subject, while the net magnetization vector of the subject is aligned along the longitudinal axis of the main magnetic field. The MR system is configured to acquire the MR data by generating at least two spin manipulating gradients for manipulating phases of nuclear spins within the subject. A vibration matching gradient is used for matching with the first state of vibration with the second state of vibration.

Abstract: Disclosed herein is a method of operating a medical system (100, 300). The method comprises receiving (200) pulse sequence commands (124) configured to control a magnetic resonance imaging system (302) to acquire k-space data (330) according to a Compressed Sensing magnetic resonance imaging protocol. The method further comprises receiving (202) magnetic resonance scan parameters that are descriptive of a configuration of the pulse sequence commands and a configuration of the magnetic resonance imaging system. The method further comprises receiving (204) an predicted undersampling factor (128) in response to inputting the magnetic resonance scan parameters into a neural network, wherein the neural network is configured to output the predicted undersampling factor in response to receiving magnetic resonance scan parameters. The method further comprises adjusting (206) the pulse sequence commands (130) to select or modify sampling of the k- space data based on the predicted undersampling factor.

Abstract: A universal joint shaft with universal joint shaft protection comprises at least one shaft element for transmitting torque, at least one protective tube element arranged around the shaft element, and an intermediate bearing, by means of which the shaft element is rotatably mounted about an axis of rotation (L) in the protective tube element, wherein the intermediate bearing comprises an outer ring fixed to the protective tube element and an inner ring fixed to the shaft element, which are rotatable relative to each other, and a clamping mechanism by means of which the inner ring is fixed on the shaft element.

Abstract: The invention relates to a magnetic resonance system (100) configured for acquiring magnetic resonance data from a GC subject (118). Execution of the machine executable instructions (140) stored in a memory (134) causes a processor (130) to control the magnetic resonance system (100) using a set of waveform and pulse sequence commands (142, 152) to prepare a first state of vibration (211) of the one or more hardware elements and/or the subject (118). The preparing comprises generating the vibration matching gradient (200) inducing the first vibrations (210) of the one or more hardware elements and/or the subject (118), while the net magnetization vector of the subject (118) is aligned along the longitudinal axis of the main magnetic field. The magnetic resonance system (100) is further controlled to acquire the magnetic resonance data (144, 154) according to a magnetic resonance protocol.

Abstract: A torque limiting coupling is arranged rotatably around a longitudinal axis. The torque coupling comprises at least one locking element that is displaceable between a locking position and an unlocking position and that is biased towards the locking position. The locking element is transferable into the locking position in the decoupling position of a switching disc, in which locking position the locking element is supported in a circumferential direction on a coupling hub and on the switching disc, and in which the switching disc is locked against rotation relative to the coupling hub. The at least one locking element is further transferable into the locking position when the switching disc is in its coupling position wherein, in the locking position, the locking element is supported in a circumferential direction on the coupling hub and the switching disc, and the switching disc is locked against rotation relative to the coupling hub.
