Abstract
The invention relates to a medical X-ray devicearrangement for producing three-dimensional information of an objectin a medical X-ray imaging medical X-ray device arrangement comprising an X-ray sourcefor X-radiating the object from different directions and a detectorfor detecting the X-radiation to form projection data of the object. The medical X-ray devicearrangement comprises: to produce three-dimensional information of the object, the prior distribution p(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 object
