Path integrals and optical tomography

چکیده
We make use of the path integral representation of the diffusion Green’s function to derive a renormalized perturbation expansion for the propagation of diffuse waves in an inhomogeneous medium. The first term in the expansion coincides with the Rytov approximation. The higher order terms can be used to develop a direct reconstruction method for time-resolved optical tomography.

An algorithm for real-time tomography of gas concentrations, using prior information about spatial derivatives
We present a new computed tomographymethod, the low third derivative (LTD)method, that is particularly suited for reconstructing the spatial distribution of gas concentrations from path-integral data for a small number of optical paths. The method "nds a spatial distribution of gas concentrations that (1) has path integrals that agree with measured path integrals, and (2) has a low third spatia...

In fourier domain optical coherence tomography, we can measure the optical thickness ( refractive index n times thickness d), to obtain the retinal layers in order to diagnose many disorders. In this work, we introduce a new method for measurement of refractive index and physical thickness of multiple layers simultaneously by Fourier domain optical coherence tomography, without additional infor...
متن کاملA Tomographic Method for the Reconstruction of Local Probability Density Functions
A method of obtaining the probability density function (PDF) of local properties from path integrated measurements is described. The approach uses the discrete probability function (DPF) method to infer the PDF of the local extinction coefficient from measurements of the PDFs of the path integrated transmittance. The local PDFs obtained using the method are compared with those obtained from dir...

Introduction: Different approaches have been developed to find the position of the internal auditory canal (IAC)in middle cranial fossa approach. A feasibility study was performed to investigate the combination of cone beam computed tomography (CBCT), optical coherence tomography (OCT), and laser ablation to assist a surgeon in a middle cranial fossa approach by outlining the internal auditory ...
