Calculate plasma radioactivity curves ratio with this program. dftdv help you calculate the ratio of tissue and plasma radioactivity curves, for example distribution volume as a function of time.
Note that this is not the same as equilibrium distribution volume, but it may become very close to it if the ratio reaches a steady phase. Calibration units or adequate sampling time ranges or frequency are not verified by the program.

Usage: dftdv <Tissue file> <Plasma file> <Output datafile>
