Abstract

Abstract

The principle of penumbral imaging is experimentally validated based on the microfocus X-ray source. Using pinhole imaging, the microfocus source is directly measured; then the basic principles of penumbral hole imaging, penumbral cone imaging and penumbral ring imaging are introduced, as well as the penumbral imaging results on the microfocus sources and Wiener filtering reconstruction results. According to the results, the diagnostic capability of penumbral cone is the same with penumbral hole imaging, the size of the reconstruction image agrees with that of the source image, and the diagnostic capability of penumbral ring imaging is better, the size and shape of the reconstruction image are closer to that of the source image.
