Abstract

La presente invención se refiere a un tubo de rayos X con una configuración de compensación activa. Con objeto de proporcionar compensación mejorado para un descompensación minimizado durante la operación, se proporciona un tubo de rayos X (10) con una configuración de compensación activa (12) que comprende una configuración de ánodo giratorio (14), una configuración de cojinete (20, 22, 24), una configuración de conducción (26, 28, 30) para girar la configuración de ánodo, una configuración de detección de descompensación (32) , y medios de compensación activa (34, 36, 38, 40, 42) La configuración de cojinete se proporciona como un cojinete fijo de la configuración de ánodo giratorio para apoyar la configuración de ánodo giratorio. La configuración de detección de descompensación se configura para detectar una descompensación del ánodo. Los medios de compensación activa son medios de compensación electro-magnética configurados para proporcionar un campo magnético y para aplicar fuerzas magnéticas de excentricidad a la configuración de rotación.
