1. A system, comprising:
a memory, wherein the memory is configured to store machine executable instructions, wherein the memory further stores a neural network, wherein the neural network is configured to output a predicted undersampling factor for magnetic resonance imaging in response to receiving magnetic resonance scan parameters, wherein the magnetic resonance scan parameters are descriptive of a configuration of a magnetic resonance imaging system; and
a computational system, wherein the computational system is configured to control the magnetic resonance imaging system, wherein execution of the machine executable instructions causes the computational system to:
receive pulse sequence commands, wherein the pulse sequence commands are configured to control the magnetic resonance imaging system to acquire k-space data according to a Compressed Sensing magnetic resonance imaging protocol;
receive the magnetic resonance scan parameters;
receive the predicted undersampling factor in response to inputting the magnetic resonance scan parameters into the neural network and prior to the acquisition of k-space data;
adjust the pulse sequence commands to select or modify sampling of the k-space data based on the predicted undersampling factor; and
store the adjusted pulse sequence commands in the memory.
