In circular-scanning-based photoacoustic tomography (PAT), the effect of finite transducer aperture has not been effectively resolved. The goal of this paper is to propose a practical reconstruction method that accounts for the finite transducer aperture to improve the lateral resolution.

提高圆形扫描光声层析成像横向分辨率的近似反投影方法

在基于圆形扫描的光声断层扫描 (PAT) 中，有限换能器孔径的影响尚未得到有效解决。本文的目标是提出一种实用的重建方法，该方法考虑到有限换能器孔径以提高横向分辨率。
