摘要 为了研究不同角度扫描对光声层析成像分辨率的影响,采用了数值仿真计算,得出了不同角度扫描与分辨率之间的经验公式,即扫描角度大于100°时,分辨率几乎没有变化,当扫描角度小于100°时,分辨率降低非常明显。该研究结果对光声成像扫描轨迹的设计、成像效果评估具有较好的参考价值。 In order to study the influence of photoacoustic tomography resolution from different scanning angle, numerical calculation is carried out. An empirical formula is provided to approach our numerical results, The resolution is almost unchanged when the scanning angle is greater than 100~; however it decreases for less than 100~ scanning angle. The results are helpful for design of scanning trajectory and evaluation of reconstruction in the photoaeoustie imaging field.
