A computer system for cytology in a private laboratory using a PDP 8/E minicomputer.

A computer software package written in Dibol for a PDP 8/E computer is described that is designed for the needs of the cytology department of a moderate-sized private medical laboratory. Computerized accessioning of cases, report preparation and printing, historical filing, activity summary reports, and direct patient and physician billing are provided by the relatively inexpensive system. The software has been in use for over two years in our cytology department and has resulted in increased efficiency, cost-effectiveness, and quality of reports.

On-line computation of cardiac output with the thermodilution method, using a digital minicomputer.

In the present study, several techniques for calculating cardiac output were evaluated in order to find an accurate technique suitable for on-line digital computation. The thermodilution method was evaluated by different calculation techniques and by comparing these techniques with electromagnetic flowmeter values. Comparison of thermal dilution curves, manually calculated by the log-normal and the exponential assumption, showed a correlation coefficient of 0.978 between the two methods, the former values being 11% higher. The exponential method correlated very well with the technique, using a correction factor for injection errors (r = 0.999). Since the exponential technique correlated well with the electromagnetic values (r = 0.84) and since it was less complicated than the technique, using correction factors, this technique was chosen for automation. Comparison of exponential calculated thermodilution values with a digital computer and manually, showed a correlation coefficient of 0.991. Therefore, it was concluded that on-line computation of thermodilution curves improves the applicability of the termodilution techniques as a means of measuring cardiac output.

Interactive image processing with an off-line minicomputer: organization, performance and applications.

A recently established facility for interactive image processing is described, primarily from the point of view of the system's hardware organization and the special purpose software provided to support it. The performance of more general software (the 'Semper' system) in the new environment has been measured carefully, and found to be about 10 times its performance on our previous PDP 8/E computer; particular attention is given to the data management techniques crucial to the system's efficiency. Some current applications are illustrated, including high resolution image interpretation and image averaging of biological crystals.
