There are several MR imaging procedures that result in three-dimensional data of moving spins. One way to evaluate these data is a sequential observation of 2D slices. A more common and efficient approach is to retrospectively calculate two-dimensional projection images at different angles representing individual views of the tomographic volume. The display of different views from the same data set will allow a realistic visualization of the blood vessel anatomy.
有几种磁共振成像程序可生成移动自旋的三维数据。评估这些数据的一种方法是对二维切片进行顺序观察。一种更常见且高效的方法是回顾性地计算不同角度的二维投影图像,这些图像代表断层体积的各个视图。从同一数据集显示不同视图将能实现血管解剖结构的逼真可视化。
