摘要： According to an exemplary embodiment of the present invention, an iterative reconstruction of coronary arteries comprises a filtering of projection data on the basis of a top-hat filter and an iterative reconstruction of the object of interest on the basis of a regularisation favouring sparse objects. This may provide for high contrast and detail.
