title: Edge enhancement of computed tomograms by digital unsharp masking.
abstract: Edge enhanced images can be produced on existing commercial computed tomographic equipment by a method called "digital unsharp masking" without any expense or computer software development. This technique permits display of anatomic areas having an extremely wide range of densities, while making edge detail more apparent.
