Computed radiography (CR) is a digital technology that employs reusable photostimulable phosphor (PSP) imaging plates (IP) to acquire radiographic images. In CR, the x-ray attenuation pattern of the imaged object is temporarily stored as a latent cha

Direct flat-panel detectors using amorphous selenium (a-Se) x-ray photoconductors are gaining wide-spread clinical use. The goal of our investigation is to understand the physical mechanisms responsible for ghosting, i.e., x-ray induced change in sen

A new pixel readout architecture is presented for amorphous selenium (a-Se) direct conversion radiation detectors. Photon-counting operation provides excellent sensitivity to low radiation doses but saturates the system at medium to high doses due to
