Cupping artifacts caused by x-ray scattering can seriously impact the quality of reconstructed images in cone-beam computed tomography (CBCT). The methods that can reduce and control the x-ray scatter is desired urgently. We propose a new scatter correction method based on the beam attenuation grid (BAG) technique. The new method which combines image sequence processing and Guassian Blurring is designed...
The mammography has the problem of overlapping of cancer symptoms with normal tissue structures. A cone-beam Computed Tomography (CBCT) may partially solve this problem. One cone-beam breast CT (CBBCT) prototype has built up successfully and the primary performance evaluations have been done. All components including the X-ray tube, rotation stage and flat detector are connected together and controlled...
