RLE Images and DICOM files

[antonybates]

Hi everyone,
I need a little help. I am loading DICOM files but I'm having trouble extracting RLE compressed data. I know how to decompress the data itself but do not know how/where it is stored in the DICOM file.

Any idea?

Thanks,
Tony

Hi,
I am working on a project where I need to read in DICOM files and convert them to RAW image format. I am absolutely new to this area. In fact, very much new to file I/O itself. I saw your post and am guessing that you have worked on DICOM before. I would be obliged if you could refer me to any resources on the web which will help me in reading DICOM files and converting them to RAW files...like file structure,etc. Thank You, Aditya

Hi,
Yes, I have been doing quite a bit of work in the DICOM area. Some of the most useful resources I have come across are as follows:

* Overview of DICOM files and some useful links
http://www.psychology.nottingham.ac.uk/staff/cr1/dicom.html

* Java source code from freeware software ImageJ for loading of DICOM files.
http://rsb.info.nih.gov/ij/docs/source/index.html

* DICOM sample files for testing
http://www.barre.nom.fr/medical/samples/

These are probably some of the best resources if you are just starting out in the field of DICOM.

Tony.

I have little knowledge in the organization of DICOM file format myself. However I suggest you download a very useful image viewer (IrfanView) at:

http://www.tucows.com/preview/194967.html

It's free and it supports DICOM. It has a very useful HEX viewer, so I guess you can open a DICOM in HEX and try to figure out where the data starts. Hope it helps.
