摘要：
This design note describes an inexpensive system used to control the radiofrequency field generated by magnetic resonance coils. The device is built around three main modules, a sequencer, a modulator and a phase-sensitive detector. This system permits one to detect the radiofrequency field at each point of the region of interest using a pick-up coil, without the requirement of a magnetic resonance spectrometer. Examples of radiofrequency field distributions obtained at 85 MHz are given.
