    Abstract: A housing of an electronic cassette has an inclined surface which is formed between a side surface and a rear surface thereof and inclined relative to the side surface and the rear surface. An antenna opening through which a radio wave is transmitted is formed on the inclined surface. Since the antenna opening is formed on the inclined surface, the antenna opening is not blocked by a rear plate of a holder of an upright radiographic stand or a supine radiographic stand, and the antenna opening is not blocked by a side panel of an outer grid. Both in the case where the electronic cassette is set to the holder and in the case where the outer grid is attached to the electronic cassette, it is possible to perform stable wireless communication.

    Abstract: A derivation unit derives imaging conditions corresponding to virtual grid characteristics (grid ratio) received by a receiving unit on the basis of a table stored in a storage unit. The derivation unit sets the derived imaging conditions in a radiation source control unit. The radiation source control unit controls a radiation source on the basis of the set imaging conditions such that a radiographic image is captured. An execution unit of an image processing device acquires the radiographic image captured by the radiation detector through a detector control unit. The execution unit performs a virtual grid process for the acquired radiographic image on the basis of the virtual grid characteristics received by the receiving unit and the imaging conditions derived by the derivation unit to generate a radiographic image from which the influence of scattered radiation has been removed and displays the radiographic image on a display unit.

    Abstract: In an image analysis device, an image analysis method, and a non-transitory computer-readable recording medium, it is determined whether a radiographic image is captured by rocking a rocking imaging grid. The image analysis device includes: a radiographic image acquisition section; a dosage data acquisition section that acquires dosage data indicating, in a time-series manner, a dosage of radiation rays exposed to a specific position in an imaging area in a specific period; and a determining section that determines whether the dosage data has a first feature indicating a dosage variation as a plurality of radiation absorbing bodies and a radiation transmitting body disposed between adjacent radiation absorbing bodies pass through a space between the specific position and a radiation source, and determines that the radiographic image corresponding to the dosage data determined to have the first feature is a rocking grid use image captured by rocking a rocking imaging grid.
