摘要
为了研究在不同方位探测光声信号对光声层析成像的影响, 采用了数值仿真计算, 得出了在有限角度扫描的情况下, 吸收体分布与探测方向呈45度夹角时, 成像效果较好; 在条件允许的情况下, 采用全方位探测扫描, 其成像效果最好。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。
Abstract
In order to study the influence from different detected-azimuth on photoacoustic imaging, numerical calculation is carried out. The results indicated that the good quality of photoacoustic imaging can be obtained when the angle between absorbers and detected direction is 45° for a limited-view scanning, and better quality of photoacoustic imaging can also be obtained in full-view scanning subject to the respective conditions. These are helpful for the choice of scanning radius and the evaluation of reconstructed images.
