Role of sensor sensitivity in photoacoustic tomography (PAT) imaging is discussed. In this study, sensitivity profile (apodization) of nite size sensors was considered as axisymmetric and modelled by using a Gaussian function. The full width at half maximum (FWHM) of the Gaussian function was varie...
