Evaluation of the OSC‐TV iterative reconstruction algorithm for cone‐beam optical CT

Purpose: The present work evaluates an iterative reconstruction approach, namely, the ordered subsets convex (OSC) algorithm with regularization via total variation (TV) minimization in the field of cone‐beam optical computed tomography (optical CT). One of the uses of optical CT is gel‐based 3D dos...
