| Abstract | The invention relates to a tomographic apparatus for the three-dimensional modelling of an object to be imaged, said tomographic apparatus comprising at least one irradiation source for irradiating the object to be modelled from at least two different directions, and at least one receiving means for receiving the radiation transmitted through the object. The reconstruction parameter is a parameter which determines the behavior in iteration of a reconstruction representing the object to be modelled. The tomographic apparatus comprises means for modelling an object to be imaged by using a non-iterative tomographic modelling algorithm for determining reconstruction parameters for a more accurate computation to be conducted with an iterative tomographic modelling algorithm, in which the computation is conducted from a region of interest in the object. |
