发明名称 Radiographic imaging system
摘要 There is provided a radiographic imaging system that has: a radiographic imaging device at which fluoroscopic imaging, that carries out capturing of radiographic images continuously, is possible; a radiation irradiating device that irradiates radiation in a pulse form with respect to the radiographic imaging device at a time of fluoroscopic imaging; and a controller that controls the radiation irradiating device such that radiation is pulse-irradiated at the radiographic imaging device with a proportion of an irradiation time period of radiation being set within a range of 12.5% to 80% with respect to each frame time period for capturing respective frame images according to a frame rate of fluoroscopic imaging, while capturing of radiographic images is carried out at the radiographic imaging device synchronously with the pulse irradiation.

主权项 1. A radiographic imaging system comprising: a radiographic imaging device that is configured to perform fluoroscopic imaging comprising continuous capture of radiographic images; a radiation irradiating device that irradiates radiation in pulse form with respect to the radiographic imaging device at a time of fluoroscopic imaging; and a controller that controls the radiation irradiating device such that radiation is pulse-irradiated at the radiographic imaging device with a proportion of a radiation irradiation time period being set within a range of 12.5% to 80% with respect to each frame time period for capturing respective frame images according to a frame rate of the fluoroscopic imaging, while the capture of radiographic images is performed at the radiographic imaging device synchronously with the pulse irradiation, wherein the controller controls the radiation irradiating device to set the radiation irradiation time period with respect to each frame time period such that, in a case in which a frame rate of fluoroscopic imaging is less than or equal to a first frame rate threshold value, radiation is pulse-irradiated with the proportion of the radiation irradiation time period with respect to each frame time period being set at a first proportion, and, in a case in which the frame rate of fluoroscopic imaging is less than or equal to a second frame rate threshold value that is lower than the first frame rate threshold value, radiation is pulse-irradiated with the proportion of the radiation irradiation time period with respect to each frame time period being set at a second proportion that is different from the first proportion.
