ABSTRACT:
The invention relates to a medical X-ray device5arrangement for producing three-dimensional information of an object4in a medical X-ray imaging medical X-ray device arrangement comprising an X-ray source2for X-radiating the object from different directions and a detector6for detecting the X-radiation to form projection data of the object4. The medical X-ray device5arrangement comprises:means15for modelling the object4mathematically independently of X-ray imagingand means15for utilizing said projection data and said mathematical modelling of the object in Bayesian inversion based on Bayes' formulap(xm)=ppr(x)p(mx)p(m)to produce three-dimensional information of the object, the prior distribution ppr(x) representing mathematical modelling of the object, the object image vector x, which comprise values of the X-ray attenuation coefficient inside the object, m representing projection data, the likelihood distribution p(m|x) representing the X-radiation attenuation model between the object image vector x and projection data m, p(m) being a normalization constant and the posteriori distribution p(x|m) representing the three-dimensional information of the object4.
