An Approximate Point-Spread Function for Electrical Impedance Tomography Imaging

In Electrical Impedance Tomography, the ill-posed nature of the inverse problem and the interaction between the electric current and objects cause poor spatial resolution and blurring in the reconstructed images. This study proposes a numerical method, called the voltage-dependent point-spread funct...
