| description | PURPOSE:To know the precise distribution of a radioactive accumulating amount through the simple comparison of light emitting intensity and to read a radiophotograph satisfactorily by providing an integration circuit which integrates light emitting intensity at every pixel unit and obtains the light emitting intensity by using a unit pixel as a reference. CONSTITUTION:Reading image information is performed by peripheral scanning at every prescribed period. Since a peripheral speed in scanning an inner periphery Ro is lower than that in scanning an outer periphery Rm, a decrease in information reading quantity per unit time occurs. Therefore, even when light emitting intensity regarding unit pixels Gm,n-Go,o with the same radioactive accumulating amount is detected, the light emitting intensity detected by one reading action becomes lower as the periphery comes to the inner side Ro. However, the detected light emitting intensity is integrated by the integration circuit at every pixel unit Tm,n-Go,o, whereby the light emitting intensity in proportion to the actually integrated radioactive amount can be obtained by using a unit pixel as a reference. Thus, by the simple comparison of the light emitting intensity, the precise distribution of the radioactive accumulating amount can be found, and a radiograph can be read out satisfactorily. |
