DCMCHECK and SR verification

[Ashutosh]

While running DICOMCheck on one of the Adult Echocardiography SRs, I ran into this problem.

DCMSR - Error: Cannot add "has acq context CODE" to NUM in Comprehensive SR
DCMSR - Error: Reading content item CODE "1.4.2.2.3" (Invalid by-value Relationship)

 But In the DICOM Standard, TID 5203 clearly identifies that HAS ACQ CONTEXT, CODE, Image View is a valid relationship with a parent measurement. Not sure, what we are doing wrong here or it’s a bug on the DCMCheck?

[Jörg Riesmeier]

There was an inconsistency in the DICOM standard that has been fixed with CP 571 - after the release of your DCMCHECK version, I guess.

From the DCMTK 3.5.4 CHANGES file:

Code: Select all

**** Changes from 2005.07.27 (riesmeier)

- Added provisional support for CP571, i.e. allow certain relationships needed
  for TID 5203 (Echo Measurement).
  Affects: dcmsr/libsrc/dsrcomcc.cc
           dcmsr/libsrc/dsrenhcc.cc

Thanks for your answer Jorg. I work for Siemens and we have a licensed version for DCMCHECK 2.0.0.

How can we upgrade to the latest version that you quote?

thanks

[Jörg Riesmeier]

DCMCHECK 2.0.0 is still the current version. We are working on a significantly enhanced and updated version 3.0 but there are still several things to do before we can release this version.

The change log entry that I quoted in my last posting refers to the underlying DICOM toolkit DCMTK and not to DCMCHECK. However, since Siemens (MED AX) also bought the source code of DCMCHECK, it should be possible to fix the described issue before.
