Photometric Interpretation and DICOM Exports

Hi there

Always wanted to congratulate you for the excellent viewer. Its one of the most practical and fast DICOM viewers, obviously because its designed by a Radiologist.

Two things I wanted to bring to your notice

1. We have an HD 15 Philips USG machine. The non doppler images are wrongly represented in Radiant possibly due to a parsing error of the COLOUR PALETTE Photometric Interpretation. Surprisingly the colour doppler images are correctly represented. The other newer USGs don't have this problem. Is there anything that can be done about it?

2. I sometimes export DICOM series using Radiant. It would be wonderful if we had an option not to compress the the PixelData. The JPEG compressions are not handled by Python libraries.

I am myself a radiologist and do a little bit of image analysis.

Keep up the good work.

Dratoms, thank you for your nice comment!

1) Would it be possible for you to send us two sample images (one with a correct and one with an incorrect presentation)? If so, please contact us directly:

2) Currently DICOM export works simply by copying the source files. So the change of the transfer syntax is not possible. We will add such option in future versions.

Take care!

Dratoms, use dcmdjpeg to dejpeg your dicom files, if you know how to use python you will figure out how to use that tool on your files recursively.

For instance bash
find . -type f -printf "dcmdjpeg %p %p \n" | bash

But can be easily done in Windows cmd or PowerShell too.

There is also a wrapper (pypx) for dcmtk in python. But I do not know if it implements the dejpeg functionality.
