An Efficient Method for Model Reduction in Diffuse Optical Tomography
We present an efficient method for the reduction of model equations in the linearized diffuse optical tomography (DOT) problem. We first implement the maximum a posteriori (MAP) estimator and Tikhonov regularization, which are based on applying preconditioners to linear perturbation equations. For model reduction, the precondition is split into two parts: the principal components are consid...
متن کاملBreast Cancer Detection with Diffuse Optical Tomography
3 ACKNOWLEDGMENTS First, I would like to thank Professor Huabei Jiang, for his continuous support, trusts and precious advice during my study for the Ph.D. Professor Jiang is well-known in the field of optical tomography. His views and understandings on the research subjects are exceptional. As a professor, although his schedule is very tight, he is always available to help me on my research wh...
متن کاملDomain decomposition method for diffuse optical tomography
Diffuse optical tomography is modelled as an optimization problem to find the absorption and scattering coefficients that minimize the error between the measured photon density function and the approximated one computed using the coefficients. The problem is composed of two steps: the forward solver to compute the photon density function and its Jacobian (with respect to the coefficients), and ...
متن کاملIterative boundary method for diffuse optical tomography.
The recent application of tomographic methods to three-dimensional imaging through tissue by use of light often requires modeling of geometrically complex diffuse-nondiffuse boundaries at the tissue-air interface. We have recently investigated analytical methods to model complex boundaries by means of the Kirchhoff approximation. We generalize this approach using an analytical approximation, th...
متن کاملMulti-spectral and Fluorescence Diffuse Optical Tomography of Breast Cancer
Multi-spectral and Fluorescence Diffuse Optical Tomography of Breast Cancer Alper Corlu Arjun G. Yodh Multi-spectral and fluorescence diffuse optical tomography (DOT) techniques are explored and applied to image human breast cancer in vivo. Image reconstruction algorithms that utilize first and second order gradient information are described in detail. Breast DOT requires large computational me...
