A Real-Time Data Monitoring and Accumulation System for Dynamic Studies with Radionuclides

Conference:

Abstract

A multipurpose digital data monitoring and accumulation system is described. The central unit of the system is a PDP-8 computer with a 12K memory. The system contains furthermore a multipurpose digital input/output register for low data rates, a fourfold and a twofold ADC connected to the high-speed multiplexor unit of the PDP-8 and a digital timet. Data from various process peripheries are recorded on a nine-track IBM compatible Ampex tape recorder. When two co-ordinates are recorded the system is used in the ''add-one-to-storage'' mode. In the case of more than two co-ordinates the data are stored in the sequential mode, event by event. A dialogue real-time monitor program in assembler language was developed to control the process peripheries. The 4K-Fortran operating system was modified in such a way that monitor subroutines were called into the Fortran program without loss of the real-time properties of the monitor system during a Fortran run. The use of the system for lung function studies with an Anger-type scintillation camera and {sup 133}Xe is discussed as an example of the application of the system. (author)
