Abstract (en)
[origin: US4675891A] The invention relates to an X-ray apparatus with focus position control, the focus being formed on the anode of an X-ray tube with magnetic bearings. The X-ray apparatus comprises a focus position sensing device cooperating with electronic means associated with the magnetic bearings, in order to control the position of the focus by displacing a rotor under the action of the magnetic bearings.
Abstract (fr)
L'invention concerne un dispositif radiologique à asservissement en position d'un foyer, ledit foyer (f) étant formé sur l'anode (9) d'un tube radiogène (3) à paliers magnétiques (PM1, PM2). Le dispositif radiologique (1) comporte un dispositif capteur (14) de position de foyer coopérant avec des moyens électroniques (12) associés aux paliers magnétiques (PM1, PM2), pour asservir la position dudit foyer (f) en déplaçant un rotor (8) sous l'action desdits paliers magnétiques (PM1, PM2).
