hi ,

I am tring to display DICOM image using .net.
I am using following code.

Bitmap bmp = new Bitmap(512, 512,
System.Drawing.Imaging.PixelFormat.Format16bppGray Scale);

It is giving error........

Which PixeFormat I have to use if bits allocated=8 and bits Stored=8.

or if bits allocated=16 and bits Stored=12.

Thanks,

Rupali.

Ha. The GDI+ provider of graphics in .Net land does not support 16bpp
gray scale - not that it would matter. How many shades of gray can a
human see anyway?

You will need to work with the VOI LUT (window center and window width),
allowing your user to adjust them in some fashion - the current fashion
seems to be through grabbing the mouse and tracking mouse movement
left/right and up/down. Take a look at KPACS and/or Clear Canvas
"windowing" functions.

Now, this isn't particularly difficult - the hard part comes in trying
to do this in a performance kind of way. I'm currently studying the
code in ClearCanvas - they seem to be more adept at performance with
large 16bpp mammo images than what I can muster...
