How can I fix "unable to convert dataset from 'JPEG Baseline' transfer syntax to 'Little Endian Explicit'" while using DCMTK-Toolkit?

Question

I'm trying to send an image as a DICOM-file ((0002,0002) Media Storage SOP Class UID 1.2.840.10008.5.1.4.1.1.7 --> Secondary Capture Image Storage) with the DCMTK-Toolbox storescu to the ORTHANC testserver. Therefore I converted the image with the DCMTK-function "img2dcm" to a DICOM-file in Delphi. The Image seems to be converted correctly into a DICOM-file because "MicroDicom DICOM Viewer" shows the correct image with all relevant tags. The error message I receive in the CMD is as following:

I: determining input files ...
I: checking input files ...
I: Requesting Association
I: Association Accepted (Max Send PDV: 16372)
I: Sending file: C:\Delphi5\Projects\Test_DICOM\Test_DICOM_IMG.dcm
I: Converting transfer syntax: JPEG Baseline -> Little Endian Explicit
I: Sending Store Request (MsgID 1, SC)
XMIT: W: DIMSE Warning: (MyAETitle,ORTHANC): sendMessage: unable to convert dataset from 'JPEG Baseline' transfer syntax to 'Little Endian Explicit'
E: Store Failed, file: C:\Delphi5\Projects\Test_DICOM\Test_DICOM_IMG.dcm:
E: 0006:020e DIMSE Failed to send message
E: Store SCU Failed: 0006:020e DIMSE Failed to send message
I: Aborting Association

It seems that storescu doesnt accept the (0002,0010)Transfer Syntax UID 1.2.840.10008.1.2.4.50 (JPEG Baseline(Process 1)) --> copied from MicroDicom DICOM Viewer.

I tried some network options for storescu in my Delphi-code like -xi or -xs:

Command := 'cd /d ' + dcmtkPath + '&&storescu -xs ' + IP + ' ' + Port + ' ' + DICOMPath +' +sd -ll info -aec ' +  AET +' -aet ' + edtAETitleMain.Text;

None of the options worked so far. What am I missing?

Answer 1

I just found my answer somewhere in the internet. I had to use "dcmdjpeg" from the DCMTK-Toolbox to decompress the image-DICOM-file i want to send with input the .dcm and output the same .dcm. This converted the Transfer Syntax JPEG Baseline to Little Endian Explicit.

Answer 2

Have you tried adding the flag -xy (or --propose-jpeg8) to the storescu command?

I see you used the -xs flag, but that is for lossless jpeg, and your file is lossy 8 bit jpeg (baseline 8 bit).

Answer 3

Instead of storescu, you could also use dcmsend, which is also from the DCMTK, but easier to use. In particular, there is no need to set additional command line options for sending compressed DICOM images.
