Abstract
In a method for the control of the pulse sequence for a nuclear magnetic resonance tomography system and apparatus for the implementation of the method, the calculation of a control dataset is undertaken during the running time of the sequence, so that the sequence execution can be non-deterministically controlled with minimum dwell time with optimum utilization of the gradient system.

A method for controlling a pulse sequence of a magnetic resonant system, comprising the steps of:
- in a magnetic resonant imaging system, prescribing a sequence program as a k-space structure;
- and
- generating a control dataset in a physical domain as a pulse sequence for generating magnetic field gradients, emitting radio-frequency pulses, and sampling nuclear magnetic resonant signals from said sequence program prescribed as said k-space structure during an execution time of said pulse sequence.
In a diagnostic magnetic resonant system having gradient coil sets operated by respective gradient amplifiers for emitting gradient magnetic fields, and a radio-frequency system including a radio-frequency transmission channel via which radio-frequency pulses are emitted and a radio-frequency reception channel via which magnetic resonant signals are received, the improvement comprising a controller for operating said gradient amplifiers and said radio-frequency system in a system sequence, said controller comprising a control computer which calculates a control data set for said gradient amplifiers and for said radio-frequency system during a running time of a pulse sequence from a pulse sequence program predetermined as a k-space structure.
