Abstract

In a control method and control unit to monitor a data acquisition of magnetic resonance image data of an imaging area located in a measurement volume of a magnetic resonance apparatus, an RF excitation pulse is radiated by an RF transmission/reception device of the magnetic resonance apparatus, raw data are acquired after a time after the radiated excitation pulse, by means of the RF transmission/reception device, and store the raw data, the raw data are transmitted to a monitoring unit and (a) through (c) are repeated while switching different gradients for spatial coding by readout of k-space corresponding to the imaging area along trajectories that are predetermined by the switched gradients, up to a termination criterion that is predetermined by the monitoring unit.
