Abstract:

Basic structure and work flow of pulse programmer in NMR spectrometer were introduced. The progress of pulse programmer in terms of degree of system integration, rate of data transmission and memory capacity was emphasized. The advantages and disadvantages of commercial and home-build pulse programmers were compared. A modularized pulse programmer based on USB 3.0 was proposed, which might be used in magnetic resonance imaging (MRI) scanners with multichannel transceivers.

Key words: NMR, pulse programmer, PCI-104, FPGA, USB 3.0
