A Novel Stationary CT Scheme Based on High-Density X-Ray Sources Device
With the introduction of cold electron sources such as nanotubes, X-ray sources became small in size so that many sources are installed in array to form stationary CT, which brings benefits of simplicity in mechanism and fast response.However, the nanotube-based X-ray source is still singly packaged and hence density of X-ray sources is limited, wh
