Abstract
A system for determining scan parameters includes at least one memory configured to store instructions and at least one processor configured to execute the instructions to cause the system to perform a distortion mapping sequence to generate a field map, process the field map by calculating at least one of a gradient or a higher order derivative of the field map, and determine the scan parameters based on the field map and the at least one of the gradient or the higher order derivative of the field map. The field map includes spatial information related to anticipated distortions caused by variations of a static magnetic field.
