Disclosed herein is a method of operating a medical system (). The method comprises receiving () pulse sequence commands () configured to control a magnetic resonance imaging system () to acquire k-space data () according to a Compressed Sensing magnetic resonance imaging protocol. The method further comprises receiving () 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 () an predicted undersampling factor () 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 () the pulse sequence commands () to select or modify sampling of the k-space data based on the predicted undersampling factor.

Automated adjustment of the undersampling factor

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.
