Abstract

The invention relates to a fluoroscopic computed tomography method in which measuring values are continuously acquired so as to be subjected to rebinning and filtering, after which CT images are reconstructed therefrom in a dense temporal sequence. The backprojection comprises the filtered data of fan beams which, while taking into account the data from diametrically oppositely situated zones, cover an overall projection angle range of 180°.
