Introduction to modeling

Model

Model is an explicit realization of one hypothesis about how nature works.

Model permits quantitative predictions of how the system will respond to a particular experimental protocol. If this particular hypothesis is true, the system actually responds in experiments as predicted by the model.

Role of modelling and simulation in scientific method (Phair, 1997):

Role of modeling in scientific method

In PET the mathematical models describe the dynamic behaviour of the tracer in terms of mathematical representations.
