Method and arrangement for medical X-ray imaging

摘要

A medical X-ray device 5 arrangement for producing three-dimensional information of an object 4 in a medical X-ray imaging comprises an X-ray source 2 for X-radiating the object from at least two different directions; a detector 6 for detecting the X-radiation to form projection data of the object 4 ; a computational device 15 for modelling the object 4 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. The computational device 15 utilizes said projection data and said mathematical modelling of the object in Bayesian inversion based on Bayes' formula $p\left(x,\mathrm{theta}❘m\right)=\frac{p_{\mathrm{pr}}\left(\mathrm{theta}\right)p_{\mathrm{pr}}\left(x\right)p\left(m❘x,\mathrm{theta}\right)}{p\left(m\right)}$ to produce three-dimensional information of the object.
