A self-consistent, one-dimensional solution of the Schrodinger and Poisson equations is obtained using the finite-difference method with a nonuniform mesh size. The use of the proper matrix transformation allows preservation of the symmetry of the discretized Schrodinger equation, even with the use of a nonuniform mesh. size, therefore reducing the(More)
Low exposure X-ray fluoroscopy is widely used to guide some complicate interventional procedures. Given its inherent high noise, improving the visibility of interventional devices such as stents will greatly benefit the procedures. In this study, a contrast enhancement filter has been proposed to improve stent visibility. It is designed to selectively(More)
