A method has been developed that combines dual‐energy subtraction and tomosynthesis for vessel imaging in intravenous angiography. This paper describes the procedure for doing tomosynthesis on a fan‐beam rotational‐motion system and gives the point responses of the imaging system. Phantom studies show that dual‐energy tomosynthesis improves the visualization of desired vessels lying on a selected plane. The results may be feasible for some applications such as clinical diagnosis of coronary artery diseases.
