Abstract: A radiographic image captured by irradiating a subject with radiation is acquired. A scattered radiation removal unit removes a scattered component from the radiographic image using at least imaging conditions. A correction information acquisition unit acquires correction information for correcting the degree of removal of the scattered component and changes the imaging conditions on the basis of the correction information. The scattered radiation removal unit performs a process of removing the scattered component from the radiographic image on the basis of the changed imaging conditions.

Abstract: 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.

Abstract: The present invention is capable of reducing a load of a processing operation of a user. Namely, a console first acquires an original image of a radiographic image acquired from a radiographic image capturing device, in order to perform common processing operations. The console detects common processing operations performed on an original image by the user and stores processing content of the common processing operations and the original image in association with each other. In a case in which processing transitions to individual processing (purpose A) for generating a purpose A image, the console performs image analysis process A on the acquired original image and reflects the common processing to generate an image for purpose A. Further, the console detects individual processing operations performed on the image for purpose A by the user, and performs image processing corresponding to the individual processing operations to generate a purpose A image.

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.

Abstract: 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.

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.
