Abstract

An X-ray emission device and method for a radiology apparatus comprises a cathode and a rotating anode, the anode being provided with a roughly cylindrical surface. The device forms a beam of electrons that bombards a portion of the roughly cylindrical surface of the anode that constitutes the focal point of emission of the X-rays. The position of the focal point of the anode relative to a reference position is dynamically controlled.
