关于DICOM DIR的解释在DICOM标准的那部分里有？

sakiel

它与标准的DICOM文件有何不同，请高手具体的解释一下

具体内容参见PS 3
Example 参见 PS 10

通俗点说，DICOMDIR是用来说明DICOM图象文件的内容和存储位置等信息的，一般用在光盘存储上，类似于在根目录下的索引

谢谢。还想问一下，
DICOMDIR是否只支持Implicit VR的transfer systanx.别的呢？像Explicit VR, BigEndian.

请参考DICOM Part 10
The DICOMDIR File shall use the Explicit VR Little Endian Transfer Syntax
(UID=1.2.840.10008.1.2.1) to encode the Media Storage Directory SOP Class. The DICOMDIR File
shall comply with the DICOM File Format specified in Section 7 of this Standard. In particular the:
a. SOP Class UID in the File Meta Information (header of the DICOMDIR File) shall have the
Value specified in PS 3.4 of this Standard for the Media Storage Directory SOP Class"
b. SOP Instance UID in the File Meta Information (header of the DICOMDIR File) shall
contain the File-set UID Value. The File-set UID is assigned by the Application Entity
which created the File-set (FSC role, see Section 8.3) with zero or more DICOM Files. This
File-set UID Value shall not be changed by any other Application Entities reading or
updating the content of the File-set.
