Improve image quality of X-Ray (.raw) images

We have an old commercial application that we are conforming to read this 'proprietary' format. I believe it is proprietary. It has the '.raw' extension. It is a Winform application written in C# and and an MDIParent page. There are various C++ libraries that it calls, and some 3rd party tools. But you probably will not have to deal with those too much. This software is really good at reading Canon ".cr2" raw files. But this new format, I have made it so it can read. But it is not reading that "well". I know it can do better. But I don't have time to work on it myself. This is where you come in. YOUR JOB: If you choose to accept it. Is to improve the image quality. I'm referring to 'Contrast'. Parts of the X-Ray that are too dark, but other parts that are too light. We deal in shades of in-between. How to see breaks in the bone. Can we improve the grain vs. sharpness? I realize that these smaller raw images, probably will not get us as much clarity as the .cr2, but can we try? You must adapt our code. Not some other application! The only other 3rd party application that I know that will read these files is Ifranview. And you need to tell it the size and bit rate. Notice our program comes with 'Display-Factors'. (One project in the program -- And gets installed ) Some of these can be adjusted. But have not found the magic formula. Levels I always leave at '0'. But I feel like should be less. I sometimes change the LUT -- Jpeg. And it should probably default to 'LUT-Jpeg'. Because in the code for RAW, it uses the JPEG read routines to read the '.raw' format. Code is available to the winning bidder. And a host of sample .raw images. And we will give a couple of .cr2 s as well. For comparison. Generic bids will be rejected.
