ABSTRACT
The important features of microprocessor design of medical instrumentation are discussed, and the Mammoscan dielectric breast scanner being developed in our laboratories is given as a specific example. The principles of dielectric breast scanning are explained, and the implementation of the technique in a working Mammoscan is is described. Typical results of Mammoscan examinations are given, including both normal and suspicious findings. Preliminary attempts at image classification are discussed, as well as the necessity of large-scale clinical data gathering for improving classification methods. The use of microprocessors makes devices such as the Mammoscan possible, both because of the power of microprocessor control and number handling, and because of its ability to store examination data locally and analyze it off-line at a central location.
