Abstract:
1. A method for producing three-dimensional information of an object ( 4 ) in medical X-ray imaging, characterized in that the object is X-radiated from at least two different directions and the said X-radiation is detected to form projection data of the object ( the object is modelled mathematically utilizing the projection data to solve the imaging geometry and/or the motion of the object, where the solving concerns either some or all parts of the imaging geometry and/or the motion of the object and said projection data and said mathematical modelling of the object are utilized in Bayesian inversion based on Bayes' formula  to produce three-dimensional information of the object, the prior distribution ppr(θ) representing the prior knowledge of the imaging geometry and/or the motion of the object (
