Abstract:
Methods, devices, and apparatus for determining an input voltage of an inverter circuit in a magnetic resonance imaging system are provided. In one aspect, a method includes: determining a maximum inductance voltage value corresponding to a maximum current value of a current sequence according to a relationship between inductance voltage and inductance current of a gradient coil, determining a minimum DC voltage value corresponding to the maximum inductance voltage value according to a relationship between output voltage and input voltage of the inverter circuit, and controlling the input voltage into an input terminal of the inverter circuit to have the minimum DC voltage value when the current sequence is input into a control terminal of the inverter circuit. The inverter circuit is configured to generate an AC voltage based on the input voltage and the current sequence and output the AC voltage to the gradient coil.

Claim (Index 18):
The magnetic resonance imaging system of  claim 17 , wherein the spectrum analyzer is configured to calculate a respective current sequence corresponding to an imaging sequence for each imaging scan, and\n wherein the input voltage of the inverter circuit is adjusted to have the minimum DC voltage value between an interval of two adjacent imaging scans.
