Dear colleagues, Many thanks to all of you for responding to my inquiry.
First of all, my original problem has been solved adequately. Alexander Pipelka alerted me to the -W switches for dcm2pnm; dcm2pnm -Wi 1 produced fully accurate PNG images, which I immediately burned onto a CD and express-mailed to the surgeon. aeskulap displays somewhat informative text framing around the images, but dcm2pnm doesn't. I don't know whether this framing is present in the DICOM file or is created by aeskulap, but I was hoping to have it in the captured images as well: that is why I was hoping aeskulap could be used as an image converter rather than just a viewer. I don't know what OS the surgeon's office uses, but it surely isn't Linux. They have their own (probably licensed proprietary) system for storing patient images, so they need to be able to import the images, not just view them. Thanks again, very much, for helping out with this. L Peter Deutsch
