| 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 calcula- tion 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. |
