Dicom RGB file not received correctly by the PacsOne server

Hello,

I used DCMTK's "storescu" to send the DICOM RGB file to the PacsOne server. When command line debug messages are analyzed, the files are successfully sent to the server. But the file is not stored by the server. However, the same dicom file once loaded and saved by KPACS workstation when sent using the same options, the file is correctly received and stored by the server. I guess that some of the DICOM attributes are missing or not compatible in the first case. What could be the problem ?

Following are the files that I used to sent to the PacsOne server using "storescu":
1. HipRgb.dcm
2. HipRgb-KPACS.dcm

Here,
No1 file is successfully sent but not stored in the server's database.
No2 file is successfully sent and stored in the server's database.

I compared these two files and made the attributes of No1 file as much similar as No2, but I could not solve the problem.

Note :
The PacsOne server I am using is trial version: PacsOne server Premium edition

Thank you,
Best regards

Bellow are the contents of dcm file for these two cases :

Would be interesting what PacsOne is logging when the image sent by storescu is not stored correctly. PacsOne creates the log under {PacsOne_install_dir}\log\{AETitle}.

Beside the window width and center values in HipRgb.dcm I see nothing strange in the dumps. Nevertheless, those values should not harm the storage in PacsOne anyway.

Hello,

Thanks for the response.

But its still not working !! I have checked the log files created by the PacsOne server while sending the files to it.

The error seems to be in parsing the Dicom file data elements. I have attached the log files for both the cases.

While sending "HipRgb.dcm"

So while sending the first file, a fatal error has been occured near the tag 0x0010,1010...
What may be the problem around these tags ?

By the way, the first file is created by inserting the following tags....
Also the created Dicom file is sucessfully parsed and read by all Dicom viewers.

Code: Select all

// insert the DICOM tags to create the file

The problem is the value. The attribute 'patients age' has a value representation of AS.

From the standard (PS 3.5-2008):

A string of characters with one of the following formats -- nnnD, nnnW, nnnM, nnnY; where nnn shall contain the number of days for D, weeks for W, months for M, or years for Y. Example: “018M” would represent an age of 18 months.

If you change the value to '052Y' it works with PacsOne. Btw, PacsOne reports a failure 0xA700 in the response for the bad dataset.

Another thing: the value for 'specific character set' (0008,0005) in your samples is not correct, too. It has to be 'ISO_IR 100' (see PS 3.3-2008 C.12.1.1.2 ).

Hello,

I solved the problem !

I corrected the 'specific character set' (0008,0005) value to 'ISO_IR 100'. Moreover the attribute "PatientAge" is not actually necessary in SecondaryCaptureIOD as per the definition from Dicom standard document.

It was "PatientAge" attribute that created all the problems.

Anyways, thanks for the post.
