摘要:
目的：为了实现任意斜面的选择，本文提供了一种磁共振空间定位成像的实现方式。方法：通过定位线旋转绘制功能，实现任意斜面的选择。基于LaBVIEW实现了磁共振在三维空间任意方向的定位功能，在磁共振主计算机实现夹角余弦运算，在FPGA实现了矩阵运算。本文从仿真和成像实验两方面进行了定位成像功能验证。结果：首先验证了单个平面的成像结果，然后再对任意截面进行成像，从这两方面都证明了实验结果的正确性。结论：从仿真和成像实验两方面验证了本文设计的定位功能满足成像要求。
Abstract:
Abstract: Objective To propose a method for implementing magnetic resonance spatial positioning imaging at arbitrary inclined plane. Methods The positioning line rotation function was used to realize the selection of arbitrary inclined plane. The arbitrary orientation in magnetic resonance space was realized based on LabVIEW magnetic resonance host computer did the cosine calculation of included angle and the matrix calculation was completed in FPGA. The positioning imaging function was verified through simulation and imaging experiments. Results Both the imaging of a single plane and crosssectional imaging of arbitrary plane verified the correctness of the experimental results. Conclusion The simulation and imaging experiments prove that the positioning function designed in the study meets the imaging requirements.
