Abstract
The present disclosure relates to a magnetic resonance tomography system in which the field generation unit can be replaced by a digital emulation. Activation signals of a conventional system can be provided to this digital emulation. The digital emulation of the field generation unit outputs output signals that correspond to output signals of a hardware-based field generation unit.
Claims13
A magnetic resonance imaging system, comprising:
- a physical field generator;
- processing circuitry;
- a controller configured to generate activation signals for activating the physical field generator, and to selectively provide the generated activation signals to one of the physical field generator or the processing circuitry,
- wherein, when the generated activation signals are provided to the processing circuitry, the processing circuitry is configured to receive the activation signals and to use the activation signals to generate calculated output signals that simulate output signals of the physical field generator,
- wherein, when the generated activation signals are provided to the physical field generator, the physical field generator is configured to receive the generated activation signals and to use the generated activation signals to generate physical output signals;
- and
- evaluator circuitry configured to generate image data using (i) the calculated output signals or (ii) the physical output signals.
