Some tricks with DCMTK¶
Sending uncommon or recent SOP class UIDs¶
On many systems, the storescu command from the DCMTK project is not configured
out-of-the-box to send uncommon/recent SOP class UIDs or transfer
syntaxes. You might have to fine-tune the default configuration file
of storescu in order to be able to send e.g. MPEG4 videos or
breast tomosynthesis images.
For instance, here is the result of sending one MPEG4 video on a Ubuntu 18.04 box:
$ storescu localhost 4242 XC000000.dcm
E: No presentation context for: (VVp) 1.2.840.10008.5.1.4.1.1.77.1.4.1
E: Store SCU Failed: 0006:0208 DIMSE No valid Presentation Context ID
This error message is unrelated to Orthanc (especially if you have set
the configuration option
UnknownSopClassAccepted to true). To properly adapt the
configuration file, first determine the value of the DICOM tag
SOPClassUID (0008,0016) and the transfer syntax of the file, which
can be done by using the dcm2xml command-line tool:
$ dcm2xml XC000000.dcm | grep -E 'data-set xfer|"SOPClassUID"'
<data-set xfer="1.2.840.10008.1.2.4.102" name="MPEG-4 AVC/H.264 High Profile / Level 4.1">
<element tag="0008,0016" vr="UI" vm="1" len="32" name="SOPClassUID">1.2.840.10008.5.1.4.1.1.77.1.4.1</element>
Secondly, create a copy of the default storescu.cfg configuration
file, e.g. on Ubuntu 18.04:
$ cp /etc/dcmtk/storescu.cfg /tmp/storescu.cfg
Edit this file so as to replace one of the 128 preconfigured presentation contexts, using this information:
$ diff /etc/dcmtk/storescu.cfg storescu.cfg
198c198
< PresentationContext128 = VideoPhotographicImageStorage\MPEG2
---
> PresentationContext128 = 1.2.840.10008.5.1.4.1.1.77.1.4.1\MPEG4
Obviously, you can replace more predefinitions if other pairs of SOP
class UID and transfer syntax are needed. Finally, run storescu
using this new configuration:
$ storescu -xf /tmp/storescu.cfg Default localhost 4242 XC000000.dcm
Note that the storescu command from the dcm4che project might be more easy to use in such
situations.
