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 tomographic images of the subject are generated based on the obtained plurality of radiographic images. Then, compression processing in the direction perpendicular to slice planes of the generated tomographic images is applied to the tomographic images to generate compressed tomographic images, wherein a range of the imaging directions is obtained, and a compression rate of the compression processing is set based on the obtained range of the imaging directions.

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.
