FIT TAC file format

Various mathematical functions, e.g. sums of exponential functions, rational functions, or polynomials, can be fitted to the measured PET data curves. The files in FIT file format (*.fit) can contain the parameters of different functions fitted to one or more curves.


Calculating DFT curves from function parameters

TACs can be computed from the mathematical function parameters stored in FIT files using fit2dat.

Processing FIT files

FIT file can be converted to result format using fit2res.

A function parameter in FIT file can be changed using fitedit.
