Method for determining a pulse sequence for driving a high-frequency transmitting coil
2008
Method for determining a pulse sequence for triggering a transmission high-frequency coil having a broadcast channel or a plurality of transmission channels in a magnetic resonance system, wherein the following steps are performed: - presetting a certain time for a plurality of steps of the pulse sequence control sequence for the gradient coils of the magnetic resonance system for time-dependent selection of regions of a selected layer or a selected volume, - solution of a nonlinear equation system for controlling parameters of the individual transmit channels of the transmit coil for each time step by specifying a desired target magnetization and taking account of the driving course of the gradient coils, wherein the discretized in time and space non-linear equation system resulting from the addition to the Bloch equation, includes in the control parameters, non-linear equations at least one further boundary conditions descriptive additional equation.
