Abstract
Provided is an array antenna driving method and device for a three-dimensional scanning nuclear magnetic resonance imager, wherein each antenna to be operated is driven to transmit a nuclear magnetic pulse signal by receiving a control command sent by a control system; parsing the control command to generate a pulse transmission timing signal and an antenna switching control signal; processing an externally inputted high voltage signal according to the pulse transmission timing signal to output high voltage radio frequency pulses of a plurality of channels; and selecting a high voltage radio frequency pulse of at least one channel and the antenna to be operated in the nuclear magnetic resonance pulse array antenna according to the antenna switching control signal, and superposing the selected high voltage radio frequency pulse. The device of the present invention can improve multi-layer slice information detection of signals in circumferentially different azimuth zones.
