摘要：
In this study, numerical experiments are carried out to quantitatively investigate the effects of limited-view scanning on the resolution of photoacoustic tomography. An empirical formula is provided to approach our numerical results. The results of the study are helpful for the design of scanning trajectory and the evaluation of reconstruction.
