This article is divided into two parts: the first is an opinion, the second is a description. The opinion is that diagnostic medical imaging is not a detection problem. The description is of a specific medical image-processing program. Why the opinion? If medical imaging were a detection problem, then image processing would unimportant. However, image processing is crucial. We illustrate this fact using three examples ultrasound, magnetic resonance imaging and, most poignantly, computed radiography. Although the examples are anecdotal they are illustrative. The description is of the image-processing program ImprocRAD written by one of the authors (Dallas). First we will discuss the motivation for creating yet another image processing program including system characterization which is an area of expertise of one of the authors (Roehrig). We will then look at the structure of the program and finally, to the point, the specific application: mammographic diagnostic reading. We will mention rapid display of mammogram image sets and then discuss processing. In that context, we describe a real-time image-processing tool we term the MammoGlass.
