摘要 |
A method for reconstructing an image that can be recognized stably during CAD. The method for reconstructing an image on the basis of a plurality of views of projection data items provided by X-rays having passed through a subject includes image reconstruction dedicated to a computer-aided detection (CAD) mode. The image reconstruction comprises a reconstruction function dedicated to the CAD mode, includes pre-processing that includes a noise removal filter for removing a noise from projection data, such as, a streaky artifact removal dedicated to the CAD mode, and also includes post-processing that includes a noise removal filter dedicated to the CAD mode. |
