Description

Real-time radiography systems employing an image intensifier tube have poor resolution (2 to 4 Ip/mm) compared to their film-based counterparts (10 to 20Ip/mm). Phosphor bloom, especially in the output conversion phosphor [1], is the principle cause of reduced resolution. Other systems achieve higher resolution but at the expense of additional hardware complexity [2] or use of expensive materials [3]. We are investigating software-based image restoration techniques that can cost-effectively recover resolution from existing image intensifier tube-based systems.
