Abstract:

Studies utilizing radioactive tracer microspheres to determine blood flow to a specific region, tissue, or organ under G sub z acceleration were done in this Laboratory. The microspheres were injected into animal subjects and were distributed throughout the body. They were trapped in capillary beds according to size. Tissue samples from areas of interest were taken, and radiation measured. A computer program was developed to calculate corrected counts per minute, regional blood flow, and cardiac output from raw data. This report includes a brief outline of the experimental design, the theory behind the program, execution of the program, and the program listing. Author
