Radiation image capture device, control method for erasing light source, and computer-readable storage medium

摘要

A radiation image capture device is provided that are capable of obtaining radiation images with better image quality than hitherto in both an imaging mode in which a radiation irradiation duration is comparatively short and radiation images are successively captured, and in an imaging mode in which the radiation irradiation duration is comparatively long. An erasing light source is deactivated throughout an imaging period in a first imaging mode in which a radiation detector generates image data of a radiation image based on radiation irradiated from a radiation source over a first irradiation duration. The erasing light source is activated over an imaging period in a second imaging mode in which the radiation detector generates image data of plural radiation images based on successively irradiated radiation from the radiation source over a second irradiation duration shorter than the first irradiation duration.

主权项

1. A radiation image capture device comprising:
a radiation source that irradiates radiation toward an imaging subject; a radiation detector that includes a sensor portion configured to generate charges according to radiation irradiated from the radiation source through the imaging subject, that reads charges generated in the sensor portion, and that generates image data of a radiation image; an erasing light source that illuminates the radiation detector with erasing light to erase charge remaining in the sensor portion; and a controller that, in a first imaging mode in which the radiation detector generates image data of a radiation image based on radiation irradiated from the radiation source over a first irradiation duration, places the erasing light source in a deactivated state at least from a start of radiation irradiation until completion of charge reading by the radiation detector, and that, in a second imaging mode in which the radiation detector generates image data of a plurality of radiation images based on successively irradiated radiation from the radiation source over a second irradiation duration shorter than the first irradiation duration, places the erasing light source in an activated state for at least from a start of initial radiation irradiation until completion of final charge reading by the radiation detector.
