An x-ray image reconstruction method and system ct

Object of the present invention is to provide a method for image reconstruction may be identified during stably for CAD. It includes a dedicated for image reconstruction method for reconstructing an image according to the multi-angle projection data items provided by the X-ray penetrating objects in computer-aided detection (CAD) method. The image reconstruction dedicated to the CAD system comprises a reconstruction function, the reconstruction image comprises a pretreatment, the pretreatment for removing noise comprises a noise removal filter projection data, e.g., to a CAD system dedicated stripe Artificial eraser, and after the image reconstruction process further comprises, after said treatment comprises specific to the CAD system noise cleaning filter.
