Flat panel display technology for high-performance radiographic imaging

摘要

The high fidelity display of digital medical radiographs requires devices with high detail (3000 $MUL 3500 arrays, 120 $mu@m pixels), high brightness (2000 cd/m$+2$/), and high dynamic range (400). Medical radiographic film meets these requirements when transilluminated with bright illuminators. Currently available electronic displays using CRT technology are not able to provide the needed fidelity. New flat panel emissive display technologies offer potential solutions, particularly plasma displays and vacuum microelectronic displays. The NCAICM at Sandia National Laboratories is focusing particular attention on emissive display technologies. Commercial flat panel, color systems with improved fidelity are now becoming available. Static, monochrome designs using vacuum microelectronic technology offer the potential to provide a high fidelity display for medical radiography which meets these requirements.
