Digitising intraoral radiographs

[Stuart C. White]

Keith,

We use an Epson Expression 1600 flatbed scanner at 600 dpi and are
quite pleased with the results. It is useful to use their software
Highlight and Shadow tools to get a broad range of pixel intensities
over the region of interest on the image.
