Abstract:
1. A method to generate an adapted measurement sequence for operating a magnetic resonance data acquisition unit, said magnetic resonance data acquisition unit comprising an inherent time raster that defines time durations between successive events that occur during operation of the magnetic resonance data acquisition system to acquire magnetic resonance data from a subject in the magnetic resonance data acquisition system, said method comprising the steps of: entering a predetermined measurement sequence for operating said magnetic resonance data acquisition system into a computerized device, said predetermined measurement sequence comprising a series of time slices respectively of arbitrary lengths, said time slices being selected from the group consisting of transmission type and reception type, and each time slice having a time duration associated therewith, said time duration defining a window in which at least one electromagnetic pulse is transmitted or received in said predetermined measurement sequence, said predetermined measurement sequence exhibiting global properties; in said computerized device, identifying said time raster of said magnetic resonance data acquisition system; in said computerized device, automatically determining optimization criteria for abbreviating the time duration of at least one of said time slices in said predetermined measurement sequence; for each time slice in said predetermined measurement sequence that was abbreviated by said optimization criteria, shortening the time duration thereof to a shortened time duration, each shortened time duration fitting into said time raster with no remainder and being completely within the time duration of the time slice in the predetermined measurement sequence, by satisfying said optimization criteria; and in said computerized device, automatically generating an adapted measurement sequence by replacing the time duration for any of said time slices in said predetermined measurement sequence for which a shortened time duration was determined, while maintaining said global properties of said predetermined measurement sequence, and making said adapted measurement sequence available at an output of said computerized device.
