摘要
采用核磁共振成像技术(MRI,magnetic resonance imaging)中的反转恢复自旋回波(IR,inversion recov-ery spin echo)序列对猪肉进行二维成像,从信号成像的质量效果入手,在改变成像参数的情况下分析图像变化规律。探索IR序列成像信号强度和对比度之间有相关性,得到最佳的参数。这将为今后在猪肉的保藏与加工过程中质量的评估打下良好的基础。
This article is studying the rule of the image signal data when TR parameters is changed by IR sequence in MRI system. A series of the MRI images outcome show the trend of data change. The rule between TR value and image signal value can be found. These results will be benefit for the quality analysis of meat in future work, and produce a method for food quality assessing.
