A
digital MRI system was developed using a digital oscilloscope that had a
waveform generator function. An RF pulse with 43.85 MHz Larmor frequency was
successfully output using this oscilloscope and the NMR signal was captured
using the undersampling technique (144 ns dwell time, 6.94 MHz sampling
frequency). The acquired a set of 3D MR image using a 1.0 T permanent magnet
MRI system demonstrated the validity of our approach.
