lossy compresson

[Vikash]

Hello,

Is there any way we can compress the images using lossy compression?

[J. Riesmeier]

Which compression scheme are you referring to?

[Vikash]

I want to transfer dicom images to PACS server using jpeg lossy compression.

[J. Riesmeier]

Then you could use the command line tool dcmcjpeg with option --encode-baseline to create a JPEG Baseline compressed DICOM image.

I already tried this option with tool dcmcjpeg but got this error.

I: reading input file d:\vv\1.2.840.1136982020040303004565099.4.dcm
I: DICOM file is already compressed, converting to uncompressed transfer syntax first
F: no conversion from compressed original to uncompressed transfer syntax possible!

The transfer syntax UID of the file which I am trying to convert is - JPEG 2000 Image Compression (Lossless Only) [1.2.840.10008.1.2.4.90]

[J. Riesmeier]

The public DCMTK (Open Source Software) does not support JPEG 2000 compression/decompression.
OFFIS provides an extension called DCMJP2K that fills this gap, but which is not free of charge.

[Vikash]

can you please let me know the pricing for the same? or if you can mail me to vikash.royin@gmail.com

I personally do not work for OFFIS (any longer), so please contact the people at OFFIS directly (by email): https://dicom.offis.de/people.php.en
