Abstract
A method for controlling a magnetic resonance imaging system, including: selecting a plurality of spatially non-selective initial RF-pulses each having a predefined pulse shape and a predefined frequency; determining a combined RF-pulse from the initial RF-pulses by choosing a time-offset comprising a relative application time-shift between the initial RF-pulses, wherein this time-offset is chosen such that the initial RF-pulses overlap; and including the combined RF pulse in a pulse sequence applied in a magnetic resonance imaging system.

A method for controlling a magnetic resonance imaging system, comprising:
- selecting a plurality of spatially non-selective initial RF-pulses each having a predefined pulse shape and a predefined frequency;
- determining a combined RF-pulse from the initial RF-pulses by choosing a time-offset comprising a relative application time-shift and a phase-shift between the initial RF-pulses, wherein the time-offset is chosen such that the initial RF-pulses overlap;
- and
- including the combined RF pulse in a pulse sequence applied in a magnetic resonance imaging system.
A system for controlling a magnetic resonance imaging system, comprising:
- a selector designed to select a plurality of spatially non-selective initial RF-pulses each having a predefined pulse shape and a predefined frequency;
- a determiner designed to determine a combined RF-pulse from the initial RF-pulses by choosing a time-offset comprising a relative application time-shift and a phase-shift between the initial RF-pulses, wherein this time-offset is chosen such that the initial RF-pulses overlap;
- and
- a sequence controller designed to include the combined RF pulse in a pulse sequence applied by a radio-frequency transmitter in a magnetic resonance imaging system.
