Ultrasonic CT by Finite and Boundary Element Methods

We propose a new approach to diffraction tomography. We solve the wave equation, which governs the propagation of sound through a medium with spatially varying material parameters, using a combination of the finite element method and boundary element method.

Description
Summary:We propose a new approach to diffraction tomography. We solve the wave equation, which governs the propagation of sound through a medium with spatially varying material parameters, using a combination of the finite element method and boundary element method. A computer simulation shows fine and quantitatively exact reconstruction of the two-dimensional distribution of refractive index and absorption coefficient of the material. This method is applicable not only to ultrasonic CT but also to microwave CT.
