Method to determine an acquisition sequence in an imaging method for generation of 2d slice images

An electronic control device for a magnetic resonance tomography apparatus comprising a magnetic resonance scanner configured to interact with an examination subject to acquire slice plane data from slice planes of the examination subject for generating slice images of the examination subject associated with the slice planes, said electronic control device being programmed to acquire said slice plane data by acquiring slice plane data by executing measurement sequences each comprising a preparation phase;

• and a measurement phase temporally separated from the preparation phase;
• in each measurement phase, executing at least one measurement to acquire slice plane data;
• and for n slice planes, and a set of sequence parameters comprising at least Trmin as a minimum repetition time between two measurement sequences for the same slice plane and Trmax as a maximum repetition time between two measurement sequences of the same slice plane, employing a periodic acquisition protocol comprising k data streams that, when temporarily expanded, is [TRmin, TRmax]-compatible to the k-th degree;
• and automatically determining an association of the n slice planes with the k data streams of said acquisition protocol, and an order of the slice planes within the respective data streams, using a mixed-integer linear program.

A computer-readable medium encoded with a data structure, said medium being loadable into a control computer of a magnetic resonance system to control acquisition of slice plane data of slice planes of an examination subject in an imaging method for generating slice images associated with the slice planes, said magnetic resonance system having a magnetic resonance scanner and said data structure causing said control unit to:

• acquire slice plane data by operating said scanner to execute measurement sequences each comprising a preparation phase and a measurement phase temporally separated from the preparation phase;
• in each measurement phase, execute at least one measurement to acquire slice plane data;
• for n slice planes, and a set of sequence parameters comprising at least Trmin as a minimum repetition time between two measurement sequences for the same slice plane and Trmax as a maximum repetition time between two measurement sequences of the same slice plane, employ a periodic acquisition protocol comprising k data streams that, when temporarily expanded, is [TRmin, TRmax]-compatible to the k-th degree;
• and
• automatically determine an association of the n slice planes with the k data streams of said acquisition protocol, and an order of the slice planes within the respective data streams, using a mixed-integer linear program.
