A method for the acquisition of measurement data of a breathing examination subject by magnetic resonance includes the following steps: (a) detect the physiological breathing signal of the examination subject with a breathing signal detection unit, (b) evaluate the detected breathing signal in an evaluation unit, (c) based on the evaluated breathing signal, calculate in a computer at least one parameter affecting the type of acquisition of measurement data by means of magnetic resonance, (d) detect a current physiological breathing signal with the breathing signal detection unit, (e) compare the last detected breathing signals with at least one trigger condition, (f) initiate the acquisition of measurement data using the calculated parameter from step (c) upon satisfaction of the trigger conditions from step (e), (g) repeat the steps (d) through (f) until all desired measurement data have been acquired, and (h) store and/or process the acquired measurement data in a memory and/or processing unit. After the evaluation of the detected breathing signal, at least one parameter of a following acquisition of measurement data is thus determined automatically without an input by an operator of the MR apparatus in use being required.
