A dental panoramic X-ray imaging apparatus which can use wide X-ray beams and obtain a tomographic image with a reduced level of blur is provided. By using image information detected by an X-ray image detector, tomographic images which are eight in total and correspond to plural tomographic planes arranged at predetermined intervals along the X-ray irradiation direction, for example, eight tomographic planes are calculated. Next, attention is paid to a specific one of the eight tomographic images, and a convolution process is conducted by using image information of one or more of the tomographic images, thereby removing blur from the specific tomographic image. Furthermore, the blur removal is conducted on two or more of the tomographic images, and the tomographic images from which blur is removed are summed each other so as to obtain a final synthesized tomographic image. |
