MODELING OF TOMOGRAPHY PROBLEMS USING BILINEAR SPLINES
Abstract:
The object of study is the forward and inverse tomography problems. The peculiarity of the proposed approach consists in approximating of the sensing field of tomography by bilinear spline. It is proposed to use bilinear spline for regularized solution in inverse tomography problem. Algorithms solving direct and inverse tomography problems are proposed and implemented in MatLab. Tomographic algorithms for solving problems are tested on model data. Dependence between the condition number and the layout of emitters and receivers and their number are experimentally determined. Recommendations for creating sensing field close to optimal are offered. The ways of optimizing the solution are considered.
