But while indirect panels are popular with general radiography, Colbeth notes that selenium panels have found a niche in mammography, where the market is split between cesium and selenium. Mammography requires both high dose efficiency and high resolution. For this reason, Hologic makes mammographic panels, which utilize direct conversion selenium detectors.
"In mammography, most vendors have gone with direct conversion because the resolution is higher than with indirect conversion," says Hologic's Smith. "Because X-ray energies are lower, it turns out, selenium or direct conversion materials absorb more than indirect conversion materials."

Overall, the future of digital flat panel technology is looking bright. By 2014, there will be a 55 percent increase in global X-ray system revenues, driven by an integration of digital flat panel technology into mobile X-ray systems, according to a report by research firm InMedica, entitled, "The World Market for General Radiography and Fluoroscopy X-Ray Equipment," published last February. While prices continue to fall and the development of the next generation of wireless flat panel detector technology provides further system flexibility, more customers are now able to afford the technology, the report adds.
"I think the future sees faster, higher resolution and cheaper flat panel detector technology," says Smith.
