Abstract
In an image reconstruction method for 3-d image reconstruction, particularly a fast reconstruction method for rotational angiography employing a pyramidal X-ray beam and a surface detector, image reconstruction is accomplished in a computer using an algorithm of the filtered back-projection type, and, outside the zero component, the components of the convolution kernel correspond to an exponential function. A particularly fast image reconstruction is achieved with such a convolution kernel by using recursive filtering.
