Ada software for cytometry.

Ada is a new general-purpose language that embodies the concepts of software engineering. Although it was initially developed for military purposes, it is suitable for developing software for cytometry and other health-related applications. A pilot study has demonstrated the feasibility of employing Ada for cytometry applications. Three packages were created. The first subtracts a control three-dimensional population from multiple individual experimental populations and presents the results in spread sheet form. A second package has the capability of finding aggregates of cells. The results of this package are visualized employing a commercially available program for three-dimensional presentation of the data that permits rotation in real time. A third package consists primarily of interface drivers for two commercially available personal computer boards, an ADC and a stepper motor controller. The major problems with the coding were due to incomplete implementation of the language. This pilot study, together with others, indicates that it would be both cost effective and beneficial to implement cytometry and other medical devices in Ada.
