i'm getting "out of memory" error on line using (bitmap bmp = .... how can solve that?

the "out of memory" misleading. means image format can not determined .net.

sorry .net not support dicom images. see http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.aspx info on supported image formats.
