Paper Abstract

Photoacoustic tomography(PAT) is a new imaging modality of biological tissues. It merges the contrast advantage of pure optical imaging with the resolution advantage of pure ultrasound imaging. A numerical simulation method of spatial resolution in photoacoustic tomography was studied. The full width at half maximum (FWHM) of point spread function (PSF) was calculated to determine the spatial resolution. The effectiveness of the simulation method was indicated by experiment. The relationship between spatial resolution and filter's cutoff frequency and active detector aperture size was calculated. The result could be used to calculate the spatial resolution of photoacoustic imaging system.
