Reduction of blooming artifacts in cardiac CT images by blind deconvolution and anisotropic diffusion filtering

Even though CT is an imaging technique that offers high quality images, limitations on its spatial resolution cause blurring in small objects with high contrast. This phenomenon is known as blooming artifact and affects cardiac images with small calcifications and stents. This paper describes an app...
