MRA 检查采用三维时间飞跃法，对源图像做最大强度投影重建血管影像。

MRA used 3 dimensional time of flight method and demonstrated the intra cranial arteries with the maximum intensity projection (MIP) of the source images.

原始图像先进行减影处理，再进行最大信号强度投影（MIP）重建。

The source images were subtraction from mask images followed by maximum intensity projection(MIP)reconstruction.

图像后处理以最大强度投影法（MIP）进行三维（3D）重建。

Postprocedure processing with a maximum intensity projection (MIP) algorithm was made for three dimensional (3D) reconstruction.
