✦ Synopsis

The program uses the joint Monte Carlo-Simplex algorithm for fitting the generalized, non-monoexponential model of externally detected decay of radiotracer activity in the tissue. The optimal values of the model parameters (together with the rate of the blood flow) are calculated. A table and plot of the experimental points and the fitted curve are generated. The program was written in Borland's Turbo Pascal 5.5 for the IBM PC XT/AT and compatible microcomputers.
