Over the past several years there has been an increasing interest in cone‐beam computed tomography (CT) for breast imaging. In this article, we propose a new scheme for theoretically exact cone‐beam mammo‐CT and develop a corresponding Katsevich‐type reconstruction algorithm. In our scheme, cone‐beam scans are performed along two tilting arcs to collect a sufficient amount of information for exact reconstruction. In our algorithm, cone‐beam data are filtered in a shift‐invariant fashion and then weighted backprojected into the three‐dimensional space for the final reconstruction. Our approach has several desirable features, including tolerance of axial data truncation, efficiency in sequential/parallel implementation, and accuracy for quantitative analysis. We also demonstrate the system performance and clinical utility of the proposed technique in numerical simulations.
