Abstract

Using a recently developed reconstruction method for photoacoustic tomography (PAT) valid for a planar measurement geometry parallel to a layered medium, we investigate the effects of shear wave propagation in the solid layer upon the ability to estimate Fourier components of the object. We examine this ability as a function of the thickness of the layer supporting shear waves as well as of the incidence angle of the field in the planewave representation. Examples are used to demonstrate the importance of accounting for shear waves in transcranial PAT. Error measures are introduced to quantify the error found when omitting shear waves from the forward model in PAT.

摘要

利用最近开发的适用于与层状介质平行的平面测量几何形状的光声断层扫描（PAT）重建方法，我们研究了固体层中剪切波传播对估计物体傅里叶分量能力的影响。我们研究了这种能力作为支持剪切波的层的厚度以及平面波表示中的场的入射角的函数。示例用于演示在经颅 PAT 中考虑剪切波的重要性。引入误差度量来量化在 PAT 中从正向模型中省略剪切波时发现的误差。
