Title:
放射線撮影装置
Document Type and Number:
Japanese Patent JP7424409
Kind Code:
B2
Abstract:
To suppress image quality deterioration due to a synchronization deviation between a radiation irradiation period at a radiation source and a charge accumulation period at a radiographic apparatus.SOLUTION: After reading electric charges from a plurality of radiation detection elements 7 in order to generate a frame image of a moving image, a control unit 22 of an FPD cassette 3 in a radiographic system 100 re-reads electric charges from some of the plurality of radiation detection elements 7. On the basis of amounts of the electric charges re-read from the radiation detection elements 7, the control unit 22 determines whether radiation is irradiated outside a charge accumulation period of the radiation detection elements 7. When it is determined that the radiation is irradiated outside the charge accumulation period of the radiation detection elements 7, the control unit 22 adjusts the charge accumulation period so that the radiation is irradiated inside the charge accumulation period in generation of the next frame image.SELECTED DRAWING: Figure 4
