Radiation image pickup device |
摘要 |
A radiation image pickup device comprises temperature control means for maintaining the temperature of an X ray conversion layer to be substantially constant by performing a feedback process for controlling a voltage which is applied to the Peltier element based on the temperature of the X ray conversion layer. The temperature control means starts reading out an electric charge from each pixel (DU), then converts the electric discharge to voltage with a charge amplifier and in a period until an A/D conversion process for the voltage is completed, and restricts a variation in the voltage which is applied to the Peltier element.
