METHOD AND ARRANGEMENT RELATING TO X-RAY IMAGING

To enhance results of an x-ray apparatus the invention relates to an apparatus for three-dimensional imaging of a human breast comprising a reconstruction means for reconstruction of a three-dimensional image volume, a compression paddle for holding said breast, an actuator for controlling the position of said compression paddle, and a position gauge for measurement of the position of said compression paddle. The reconstruction means is operatively arranged to receive signals, corresponding to measurements by said position gauge, from said position gauge and constrain the boundary of said image volume based on said received signal.
