Hi,

As per DICOM this is the definition of DICOMDIR.
DICOMDIR File: A unique and mandatory DICOM File within a File-set
which contains the Media Storage
Directory SOP Class. This File is given a single component File ID,
DICOMDIR.

Please refer to DICOM standards part 10 document to get more
information on DICOMDIR.
DICOMDIR does not contain other dicom files inside, but it contents
the references to the files which are contained in the File-Set for
which the DICOMDIR is made.

All the Best!

The DICOMDIR references files, rather than contains them.

The use of the DICOMDIR is defined in PS 3.10 6.2.3.3 "DICOM
Medical Information Directory", and its contents are defined
by PS 3.3 Annex F "Basic Directory Information Object Definition".

It is non-trivial to build and you will require a toolkit to do
it.

A DICOMDIR will reference those DICOM files (=DICOM File Set). See
DICOM Part 12 , Annex F. So it's not just a directory, but a special
DICOM Dataset.

As a side note, GDCM is written in C++, but offer a wrapped layer in
PHP4 (using swig):

Hi,

A DICOMDIR is not a "directory"...but a file that contains a reference
to a specific set of DICOM files (wisely called file-set). Like a
pointer to a set of files hierarchically organized tree-like in
Patient, Study, Series and Instances. This file is therefore used in
addition to all the files referenced by it to define a set of files
(for media storage, etc...). More info can be found in the Part 10 of
the DICOM standard.

hope it helps,
Jordi
