摘要
对低场核磁共振(nuclearmagneticresonance,NMR)及其成像技术(magneticresonanceimaging,MRI)的自旋回波脉冲序列在猪肉质量品评的应用研究做了初步的探索。在SE序列中,应用短重复时间TR(<500ms)和短TE(<25ms)可以得到所谓的T1加权像,在成像质量、对比度上具有明显优势。
The theory of nuclear magnetic resonance (NMR) technology is introduced. The study on the application of magnetic resonance imaging (MRI) technology about accessing the quality of pork is presented. The quality of image for TR<500 ms,TE<25 ms have obvious advantage.
