PROBLEM TO BE SOLVED: To solve the following problem: when reconstruction is performed in tomosynthesis photographing, the image quality of an oblique image is not guaranteed in an oblique cross section which does not pass through the rotation center line of the photographing, and the greater the angle of the oblique image, the more the image quality is deteriorated, thus an attention point out of a coronal plane containing a rotation center line is clearest in a coronal image and an oblique image with a larger angle becomes more blurred accordingly.SOLUTION: When a screen displaying a coronal image is switched to display an oblique image on a tomosynthesis photographing apparatus capable of displaying oblique images, input of an attention point is prompted, the input-disabled area and the input non-recommended area for the attention point are indicated on the coronal image. When the operator specifies an input-enabled area, the oblique image is displayed in the specified position.SELECTED DRAWING: Figure 1 |
