摘要
本文论述了采用低场核磁共振成像技术(magneticresonanceimaging,MRI)中的spin3D成像序列,采用不同Tau值对奶酪和面包样品进行成像实验。应用Matlab软件编程对图像进行数据处理,并对T2分布进行重建,最后得到T2分布状态图像。为核磁共振技术在食品中的应用打下良好的基础。
The images with different Tau values were gained by using a spin3D sequence under low-field nuclear magnetic resonance （NMR） image experiment. Invoking the program designed by ourselves, the magnetic resonance imaging （MRI） T2 mapping diagrams of cheese and bread samples＇ are reconstructed by software Matlab 6.5. The T2 distribution of samples were observed obviously from the T2 state mapping diagram. The results further suggests that using the programs designed by software Matlab 6.5 to reconstruct the T2 mapping diagrams is feasible,
