Summary: Electrical Impedance Tomography (EIT) aims to recover the internal electrical conductivity of a physical body from measurements of voltages and currents at the boundary of the body. EIT has applications in medical imaging, underground prospecting, and nondestructive testing. The image reconstruction problem of EIT is a nonlinear and severely ( continue reading… )
Summary: Tomography means reconstructing the internal structure of a physical body using X-ray images of the body taken from different directions. Mathematically, the problem is to recover a non-negative function f(x) from a collection of line integrals of f. Here we show how to solve the tomography problem using Total ( continue reading… )

Author of this post: Samuli Siltanen (samuli.siltanen “at” helsinki.fi) This blog aims to help everyone interested in inverse problems and their computational solution. We offer open software and links to open datasets so that anyone can easily try different reconstruction methods on both simulated and measured data. Inverse problems are ( continue reading… )
