Abstract
A total variation minimization (TVM)-based finite element reconstruction algorithm for photoacoustic (PA) tomography is described in this paper. This algorithm is used to enhance the quality of reconstructed PA images with time-domain data. Simulations are conducted where different contrast levels between the target and the background, different noise levels, and different sizes and shapes of the target are studied in a
