Paper Abstract

Computed radiography (CR) utilizing imaging plates (IPs), which consist of a photostimulable BaFX:Eu2+(X equals Cl,Br) phosphor, has found wide clinical use. In the present paper, a photostimulable SrFBr:Eu2+ (SFB) phosphor, as well as an IP employing this phosphor (SFB-IP), are experimentally prepared. A test apparatus for reading the SFB-IP is constructed, and the imaging characteristics are evaluated. The x ray imaging characteristics of the SFB-IP are different from those of the BFB-IP (the IP which consists of BaFBr:Eu2+). The difference is due to their x-ray energy absorption coefficients. Under the mammographic exposure conditions, the measurements of noise equivalent quanta as well as the visual evaluation of phantom images reveal that the SFB-IP and BFB-IP have the same quality level of imaging in spite of the PSL intensity of SFB being lower than that of BFB. However, for practical use, many problems are left on the SFB-IP and its reading apparatus.
