ABSTRACT:
A medical X-ray device5arrangement for producing three-dimensional information of an object4in a medical X-ray imaging comprises an X-ray source2for X-radiating the object from at least two different directions; a detector6for detecting the X-radiation to form projection data of the object4;a computational device15for modelling the object4mathematically 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. The computational device15utilizes said projection data and said mathematical modelling of the object in Bayesian inversion based on Bayes' formulap⁡(x,θ❘m)=ppr⁡(θ)⁢ppr⁡(x)⁢p⁡(m❘x,θ)p⁡(m)to produce three-dimensional information of the object.
