Medical applications of image analysis with the Magiscan 2.

The previous generation of image analysis machines were capable of processing and analyzing binary, i.e., black and white images, and making measurements and decisions thereon. The Magiscan 2, one of the new generation computers, is capable of analyzing gray-level images in a variety of sophisticated ways. Its uses in the medical application of image analysis are presented, as are the techniques used to analyze images in general. The two principal current medical uses are the automatic karyotyping of chromosomes and the automatic screening of cervical smears. Other applications discussed include three-dimensional reconstruction of structures from two-dimensional sections and the possibility of developing expert systems for medical diagnostics.
