Dicom图像定位相关

 

*如何确定不同序列的图像是否使用了相同的坐标系统

一般一个检查的不同序列，会使用相同的坐标系统，即各个序列可以通过位置进行关联。如果是不同的study，则一般无法共享坐标系统。

在dicom中，也可以使用tag:(0020,0052) 进行区分

Section C.7.4.1.1.1

C.7.4.1.1.1 Frame of Reference UID

The Frame of Reference UID (0020,0052) shall be used to uniquely identify a frame of reference for a series. Each series shall have a single Frame of Reference UID. However, multiple Series within a Study may share a Frame of Reference UID. All images in a Series that share the same Frame of Reference UID shall be spatially related to each other.
