Abstract
A method includes determining a position of a local coil, a coil position, and a position of a body part of a patient, a body part position. Spacing between the coil position and the body part position is determined. An optimized MR sequence is determined. Based on the determined spacing between the coil position and the body part position, it is checked that in a subsequent MR examination of the patient, a predetermined loading threshold value (e.g., an SAR value) is not exceeded. The optimization of the MR sequence thus takes place under the boundary condition that the loading threshold value is not exceeded.

A method for determining an optimized magnetic resonance (MR) sequence, the method comprising:
- determining a local coil position and a body part position, the local coil position being a position of a local coil and the body part position being a position of a body part of a patient;
- determining a spacing between the coil position and the body part position;
- determining an optimized MR sequence;
- and
- checking, based on the determined spacing between the coil position and the body part position, that in a subsequent MR examination of the patient, a predetermined loading threshold value is not exceeded.
A magnetic resonance (MR) apparatus for determining an optimized magnetic resonance (MR) sequence, the MR apparatus comprising:
- an optical detection unit or a magnetic field sensor configured to determine a local coil position and a body part position, the local coil position being a position of a local coil and the body part position being a position of a body part of a patient;
- and
- a processor configured to:
- determine a spacing between the coil position and the body part position;
- determine an optimized MR sequence;
- and
- check, based on the determined spacing between the coil position and the body part position, that in a subsequent MR examination of the patient, a predetermined loading threshold value is not exceeded.
In a non-transitory computer-readable storage medium that stores instructions executable by one or more processors to determine an optimized magnetic resonance (MR) sequence, the instructions comprising:
- determining a local coil position and a body part position, the local coil position being a position of a local coil and the body part position being a position of a body part of a patient;
- determining a spacing between the coil position and the body part position;
- determining an optimized MR sequence;
- and
- checking, based on the determined spacing between the coil position and the body part position, that in a subsequent MR examination of the patient, a predetermined loading threshold value is not exceeded.
