We measured basic imaging properties like dose attenuation ratio, photostimulated emission, resolution property (presampling MTF : MTF_<PRE>) and noise property (digital Wiener spectrum : WS_<DIG>) using various versions of HR and ST imaging plates. Resolution property was almost the same for three respective versions of the HR and ST plates. The photostimulated emission of HR III_N was higher than that of III and V by about 50% and 20%, respectively. The noise property of HR V was superior to that of other plates. In terms of the photostimulated emission of ST plates, there was no difference between III and III_N, however, that of V was about 10% higher than that of other plates. The noise property of ST V was superior to that ot III_N. ST III has a different type of structure mottle than versions III_N and V.
