Abstract:
1. Imaging system for the generation of X-ray projections of an object in real time, comprising: a) a rotational X-ray device for generating low-quality X-ray raw projections of the object from different directions with a low-dose setting over an angular range of at least 180°, and b) a data processing unit that is adapted to reconstruct a low-quality volume of interest of the object from a set of said low-quality raw projections and to calculate at least one high-quality virtual projection in an arbitrarily chosen projection direction from (i) the reconstructed low-quality volume of interest or (ii) a part of the reconstructed low-quality volume of interest in real time, wherein the high-quality virtual projection comprises integrated information of low-quality projections from different directions.
