摘要： 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.

摘要： In a radiation image processing apparatus, method, and program, performing image processing based on scattered radiation, such as scattered radiation elimination processing, accurately by taking into account the influence of scattered radiation from an area adjacent to a processing target area. For this purpose, performing image processing on a radiation image captured by applying radiation to a subject based on scattered radiation generated by the subject. In this case, a processing target area which is the processing target in the radiation image is added with another area different from the processing target area in the radiation image. Then, the image processing based on scattered radiation is performed on the processing target area using the another area and the processing target area.

摘要： A radiation image capturing system includes a radiation source and a radiation image detecting device. The radiation image detecting device includes a solid-state detector and a wavelength conversion layer disposed in this order from a radiation incident side. The wavelength conversion layer has a first phosphor layer having first phosphor particles dispersed in a binder, and a second phosphor layer having second phosphor particles dispersed in a binder. The average particle diameter of the second phosphor particles is smaller than that of the first phosphor particles. The first phosphor layer is disposed on the side of the solid-state detector relative to the second phosphor layer, and joined to or pressed against the solid-state detector. The first and second phosphor particles are distributed in the first and second phosphor layers, respectively, such that the weight of the binder per unit thickness is gradually decreased to the side of the solid-state detector.

摘要： An image obtaining unit obtains a subject image, a body thickness distribution modifying unit receives input of a virtual model having an estimated body thickness distribution and modifies the estimated body thickness distribution of the virtual model to output the modified estimated body thickness distribution, and a body thickness distribution determining unit determines the outputted estimated body thickness distribution to be used as the body thickness distribution of the subject. The body thickness distribution determining unit includes a judging unit for switching, according to a judgment condition, between a first control under which the body thickness distribution modifying process is iteratively executed until a first termination condition is satisfied and a second control under which the body thickness distribution modifying process is iteratively executed until a second termination condition that is different from the first termination condition is satisfied so that the first control or the second control is executed.
