摘要

本文介绍了我们最近研制的一种紧凑型核磁共振系统，包括射频采集系统和线圈的设计。对于采集系统，介绍了一种省时、经济的开发方法。在该系统中，采用高性能FPGA简化了电路元件。这降低了复杂性并提高了性能。我们的设计将使用Carr-Purcell-Meiboom-Gill (CPMG)回波序列脉冲序列进行NMR展示和演示。它将在尺寸和信噪比(SNR)方面与传统采集系统进行比较。

The design and implementation of a compact NMR system

This paper presents our recently development of a compact nuclear magnetic resonance (NMR) system, including radiofrequency (RF) acquisition system and the coil design. For the acquisition system, a time-saving and cost-effective method is introduced for the development. In this system, circuit components are simplified by using the high-performance FPGA. This reduces the complexity and improves the performance. Our design will be presented and demonstrated using a Carr-Purcell-Meiboom-Gill (CPMG) echo train pulse sequence for NMR. It will be compared to traditional acquisition systems in terms of size and signal to noise ratio (SNR).
