X-RAY TUBE COOLANT VOLUME CONTROL SYSTEM

摘要

An imaging tube coolant volume control system ( 14 ) for an imaging tube ( 18 ) includes a compensation tank ( 80 ) that is configured to fluidically couple an imaging tube cooling circuit ( 11 ). The compensation tank ( 80 ) includes a cooling fluid ( 17 ) and a compensation-dividing member ( 100 ). The member ( 100 ) is adjustable in response to the change in volume of the cooling fluid ( 17 ). An overflow vessel ( 82 ) is fluidically coupled to the compensation tank ( 80 ). A compensation valve ( 86 ) is coupled between the compensation tank ( 80 ) and the overflow vessel ( 82 ) and allows flow of the cooling fluid between the compensation tank ( 80 ) and the overflow vessel ( 82 ) when pressure of the cooling fluid ( 17 ) is greater than or equal to a first predetermined pressure level.
