Title (EN) METHOD AND SYSTEM FOR ADJUSTING FOCAL POINT POSITION
(FR) PROCÉDÉ ET SYSTÈME DE RÉGLAGE D'UNE POSITION DE POINT FOCAL
Abstract:
(EN) The present disclosure relates to a method and system for adjusting a focal point position of an X-ray tube. The method may include: obtaining a first thermal capacity and a first position of a focal point of an X-ray tube; obtaining a second thermal capacity of the X-ray tube; determining a second position of the focal point the X-ray tube based on the second thermal capacity; determining a target grid voltage difference of a focusing cup of the X-ray tube based on the first position and the second position of the focal point; and adjusting the X-ray tube based on the target grid voltage difference.
(FR) La présente invention concerne un procédé et un système destinés à régler une position de point focal d'un tube à rayons X. Le procédé peut consister : à obtenir une première capacité thermique et une première position d'un point focal d'un tube à rayons X; à obtenir une seconde capacité thermique du tube à rayons X; à déterminer une seconde position du point focal du tube à rayons X sur la base de la seconde capacité thermique; à déterminer une différence de tension de grille cible d'une coupelle de focalisation du tube à rayons X sur la base de la première position et de la seconde position du point focal; et à régler le tube à rayons X sur la base de la différence de tension de grille cible.
