RADIOGRAPHIC IMAGING DEVICE, RADIOGRAPHIC IMAGING SYSTEM, COMPUTER READABLE MEDIUM STORING PROGRAM FOR CONTROLLING RADIOGRAPHIC IMAGING DEVICE, AND METHOD FOR CONTROLLING RADIOGRAPHIC IMAGING DEVICE

摘要

The present invention provides a radiographic imaging device, radiographic imaging system, a program for controlling the radiographic imaging device, and a method for controlling the radiographic imaging device that may accurately detect start of irradiation of radiation even noises are generated by interference or the like. When radiation is irradiated, electric signals outputted from radiation detection pixels in charge accumulation period are detected by signal detection circuit during detection period. Control section determines whether time variation of the electric signals feature pre-specified characteristics of noise. If not, the start of the irradiation of radiation has been properly detected, the charge accumulation period continues, and radiographic image is imaged. However, if the electric signals feature the pre-specified characteristics, it is determined that the start of the irradiation of radiation has been misdetected, the charge accumulation period is stopped, and is switched to radiation detection period.

主权项

1. A radiographic imaging device, comprising:
a plurality of pixels, each pixel including:
a sensor portion that generates charges in accordance with irradiated radiation, anda switching element that, in accordance with control signals, reads out the charges from the sensor portion and outputs the charges to a signal line; a radiation detection section that outputs electric signals in accordance with the irradiated radiation; a start detection section that detects a start of an irradiation of the radiation based on the electric signals output from the radiation detection section during a detection period; a determination section that, during a radiographic imaging period after the start detection section has detected the start of the irradiation of the radiation, determines whether or not the start detection section has misdetected the start of the irradiation of radiation, based on the electric signals output from the radiation detection section; and a switching section that immediately switches from the imaging period to the detection period in a case in which the determination section determines that the detection is a misdetection.
