Abstract: A distance between a radiation source standard point indicating a position of a radiation source and a photographic subject on a standard line passing through the radiation source standard point and a detector standard point indicating a position of a detector is measured, a distance between a first reference point positioned in a first direction which is directed towards the detector standard point from the radiation source standard point with respect to the detector standard point and the detector standard point is measured, a distance between a second reference point positioned in a direction opposite to the first direction with respect to the radiation source and the radiation source standard point is measured, and a subject thickness of the photographic subject is calculated by using the distances and a distance from the distance from the first reference point to the second reference point.

Abstract: Radiographic images for different imaging directions taken by applying radiation to a subject from the different imaging directions are obtained, and a plurality of first tomographic images having a first slice thickness are generated based on the obtained plurality of radiographic images and a plurality of second tomographic images having a second slice thickness that is greater than the first slice thickness are generated based on the radiographic images. Then, MinIP processing is applied to the first tomographic images to generate a MinIP image, and MIP processing is applied to the second tomographic images to generate a MIP image. Then, combining processing is performed using the MinIP image and the MIP image to generate a composite image.
