Skull bone represents a highly acoustical impedance mismatch and a dispersive barrier for the propagation of acoustic waves. Skull distorts the amplitude and phase information of the received waves at different frequencies in a transcranial brain imaging. We study a novel algorithm based on vector space similarity model for the compensation of the skull-induced distortions in transcranial photoacoustic microscopy. The results of the algorithm tested on a simplified numerical skull phantom, demonstrate a fully recovered vasculature with the recovery rate of 91.9%.

使用矢量空间相似性模型进行光声显微镜中的头骨声像差校正：概念验证模拟研究

骷髅头代表了很高的声阻抗失配和声波传播的色散屏障。在经颅脑成像中，颅骨使接收到的波的振幅和相位信息失真。我们研究了一种基于向量空间相似性模型的新型算法，用于颅骨光声显微术中颅骨诱发的畸变的补偿。在简化的数字头骨模型上测试的算法结果表明，血管完全恢复，恢复率为91.9％。
