| 摘 要： | 阿达玛变换应用到核磁共振成象技术中,能提高成象技术的灵敏度。本文阐述了阿达玛变换在线扫描核磁共振成象中应用原理,推出了合成的激发信号相位与阿达玛编码关系。得到频率合成的激发信号相位表,据该表合成的激发信号产生多个自旋回波,能使核磁共振成象技术速度快、灵敏度高。文中还对该方法作了深入的讨论。

| Abstract: | Application of Hadamard transform in nuclear magnetic resonance (NMR) imaging enhances the sensitivity of NMR imaging. In this paper we explained the principle of line scan Hadamard transform NMR imaging and deducted the relation of Hadamard cede to the phase of excitation signals. We obtained phase table of synthesis frequency excitation signal. The Hadamard transform NMR imaging using spin echo was discussed in details. |
