Support for RDSR format from Ziehm Vision RFD 3D C-Arm

Issue #499 resolved
Tim de Wit created an issue

Modality supports RDSR, but on import I get the following error:

Traceback (most recent call last):
  File "/usr/local/bin/", line 23, in <module>

    The DICOM object doesn't contain any dose information. Was the procedure aborted? A dump with dsrdump (offis) only reveals the following information in the (invalid) object:

    dsrdump -Ec -Ee Ziehm_vision_rfd_3d_c-arm_RDSR.dcm
    W: PersonName (0040,a123) empty in content item (type 1)
    W: Reading invalid/incomplete content item PNAME "1.5"

      <has obs context CODE:(,,"Observer Type")=(121007,DCM,"Person")>
      <has obs context PNAME:(,,"Person Observer Name")="">

    A dcmdump (tag level information) confirms that it only contains the above information. I think the code should be changed to recover from the error, but an import will be impossible.

    ouwch.. should have checked that myself, sorry.
    I'll leave this issue open though for improvement of exception handling.

    Hi @tcdewit - it really does look like that RDSR might have been truncated - can you check another one to see if it is the same?

  4. Ed McDonagh

    You might want to log that with Ziehm as the DICOM conformance statement suggests that there should be an RDSR available for that model.
