METHOD AND DEVICE FOR DETERMINING A MAGNETIC RESONANCE SYSTEM CONTROL SEQUENCE

摘要

A method and a control sequence determination device for determining a magnetic resonance system control sequence are described. The magnetic resonance system control sequence includes a multichannel pulse train having a plurality of individual RF pulse trains that are to be transmitted in parallel by the magnetic resonance system over different independent radio-frequency transmit channels. The multichannel pulse train is calculated on the basis of a predefined target function with a predefined target magnetization in an RF pulse optimization method, where the target function is predefined such that the target function includes at least one local RF exposure value of an examination subject that is dependent on the control sequence. Also described are a method for operating a magnetic resonance system and a magnetic resonance system including the control sequence determination device.
