Method for correcting radio frequency signal digital amplitude and phase to control antenna arrangement of MRI system utilized to image patient body part, involves determining control signal from request signal with respect to offset value

摘要

The method involves outputting a digital control signal with a real part component and an imaginary part component to a radio frequency unit for generating a radio-frequency signal. A digital signal deviation value is received in a complex form, where the deviation value expresses a deviation of the radio-frequency signal from a request signal with respect to amplitude and a phase. The digital control signal is determined from the request signal under consideration of a signal offset value, where the real part component and the imaginary part component are separately determined. An independent claim is also included for a circuit device.
