A novel type of scintillator detector based on microfluidic technology that is used to determine the input function in real time has been proposed. Manipulation of the microfluidic geometric designs were done to determine the optimum design that can produce meaningful photon statistics. GEANT4 simulation toolkit was used to assess the key characteristics of the microfluidic scintillator detector, particularly in optimising the photon detection. It allows users to modify geometry description, physics processes, managing hit events and detector response. Modifications were done to the scintillator thickness as well as the dimensions of the microfluidic channel lengths to examines their relationships with the number of photons detected on the SIPM. The maximum depth of the positron particle in the plastic scintillator is approximately at 2.4 mm for 18F. Reducing the thickness of plastic scintillator to 2 mm may reduce photon collection by approximately 10% for 18F. By changing the microfluidic channel length from short to longer (constant volume), there is an increase of 9% photon detection. [ABSTRACT FROM AUTHOR]
