Title:
The control method and a program of the detection sensitivity of an irradiation start of a radiation image photographing instrument and radiation
Document Type and Number:
Japanese Patent JP5986443
Kind Code:
B2
Abstract:
A radiographic imaging device including: a sensor portion that generates an output signal according to an irradiated amount of irradiated radiation; a detection means that based on the output signal detects a radiation irradiation start of radiation irradiated from a radiation source during capture of a radiographic image; a noise data generation means that, based on an output signal from the sensor portion in a non-irradiation state of radiation from the radiation source, generates noise data relating to noise incorporated in the output signal; a control means that controls detection sensitivity to radiation irradiation start in the detection means according to a degree of variation in noise level expressed by the noise data; and an imaging means that captures the radiographic image after radiation irradiation start has been detected by the detection means.
