摘要： Placement of a marker is performed efficiently, when performing a plurality of radiation imaging operations of a subject with different imaging angles. An operator inputs a region of interest within a subject on a bed, via an operating section. The region of interest and a peripheral region thereof are set as an irradiation range, and the marker is placed in the peripheral region. A radiation source control section causes a radiation source to emit radiation toward the subject within the set irradiation range. Radiation which passes through the subject is obtained by a radiation image detector as a radiation image.

摘要： A tomographic image of a subject is generated from projection image data acquired in a series of image capturing processes carried out by a radiation detector based on radiation emitted from a radiation source and transmitted through the subject. An extrapolating process is performed on each of the projection image data along a prescribed direction, and a smoothing process is performed on each of the projection image data along a direction perpendicular to the prescribed direction, thereby determining values of a plurality of pixels in non-detecting regions, which do not belong to a detecting region of the radiation detector. The determined values of the pixels also are used to generate the tomographic image.

摘要： Trimming is automatically performed based on a person or persons in whom a photographer has interest. All of facial images included in a whole image are detected. Then, judgment is made as to whether each of the detected facial images is a facial image of a specific person, face information about whom is stored in a face database. If the detected facial images include a facial image or images of the specific person or persons, trimming is performed based on the facial image or images of the specific person or persons.

摘要： A radiation source is moved, relative to a detection means, in a movement range that is calculated based on a desired slice angle with respect to a predetermined base point on a base plane that defines a range of obtaining a slice image of a subject. The radiation source is moved to a plurality of positions, and a plurality of radiographic images of the subject corresponding to the plurality of positions are obtained by irradiating the subject with radiation from the plurality of positions. Further, a slice image of the subject is reconstructed from the plurality of radiographic images. When the slice image is reconstructed, radiographic images to be used to reconstruct the slice image are selected based on a distance from the detection surface of the detection means to a slice plane on which the slice image is to be generated, and the desired slice angle.
