How to change transfer syntax?

#1 Post by xfgavin »

Hi there,

I converted a jpeg into dicom using img2dcm. I found the transfer syntaxes are different between dicom header and dataset header. See below for an example:

I wonder how I can change the transfer syntax in dicom header to jpeg baseline?

Thanks.

According to the DICOM standard, the transfer syntax of the file meta information header is always "Little Endian Explicit". So, there is no need to change it. The attribute Transfer Syntax UID (0002,0010) in this meta header specifies the transfer syntax of the data set that follows the meta header.

Thanks, but when I transfer this file to our PACS (Ambra gateway) using storescu, I got error msg saying the transfer syntax does not agree between header and data-set. How should I solve this issue?

Here is the detailed err msg:
W: DIMSE Warning: (ABCD_AMBRA,RADREVIEW): sendMessage: unable to convert dataset from 'JPEG Baseline' transfer syntax to 'Little Endian Explicit'
E: Store Failed, file: baseline_year_1_arm_1_score.dcm:
E: 0006:020e DIMSE Failed to send message
E: Store SCU Failed: 0006:020e DIMSE Failed to send message

Please start storescu with option -xy (--propose-jpeg) or use dcmsend instead.

perfect, it worked!

Thank you very much!

However, when I was viewing those files on Ambra viewer, it says no image series. I guess that is something Ambra should work on.

It worked out finally because they rely on modality tag but mine was empty. I wish I asked here months earlier.
Thank you!
