Abstract:
1. A method to create a magnetic resonance image data set, comprising the steps of: operating a magnetic resonance data acquisition unit, in which a subject is located, to radiate an RF excitation pulse that causes magnetic resonance signals to be emitted from the subject; activating at least two phase coding gradients in respective spatial directions that phase code said magnetic resonance signals, each of said at least two phase coding gradients having a gradient strength; in a readout procedure, reading out said magnetic resonance signals as substantially only one raw data point in a k-space data set representing said magnetic resonance image data, at a predetermined time duration following radiation of said RF excitation pulse; setting said predetermined time duration as a maximum of a set of respective maximum time periods for each of said at least two phase coding gradients; setting a minimum time duration TE repeatedly activating said at least two phase coding gradients and radiating said RF excitation pulse and reading out substantially only one raw data point until an entirety of said k-space data set is acquired; and setting said minimum time period TE wherein i is the spatial direction of the respective phase coding direction, K
