Here's a list with quick information about DICOMDIR:
- Standard DICOM CD/DVD should have a file named DICOMDIR in its root directory.
- The DICOMDIR file has in it records that hold paths to DICOM files on the media.
- DICOMDIR is a DICOM Object holding a sequence of DICOMDIR records nodes each having a type like PATIENT, STUDY, SERIES and IMAGE
- The DICOMDIR file include key attributes from the data on the media such as Patient Name, Patient ID, Study ID, Study Date.
- The file names of DICOM files on a standard DICOM CD/DVD should be capital alphanumeric up to 8 characters with no suffix.
- The CD/DVD may include other files that are not DICOM. The DICOMDIR file does not reference them.
- The mandatory elements of the DICOMDIR nodes are not 1-2-1 with the mandatory elements in the DICOM Objects. For example Study ID which is Type 2 in DICOM Image objects is Type 1 in DICOMDIR STUDY Record. So when creating your DICOM images if you intend to create DICOMDIR for them, add these elements too.
|The first figure in the DIOM standard makes sense eventually|
It is worth staying a bit longer on this figure because it has a lot of valuable information in it so lets work it top to bottom.
