WIDE SCANNING X-RAY SOURCE

摘要

An imaging tube ( 12 ) includes a cathode ( 30 ) that emits an electron beam ( 32 ) and an anode ( 38 ). The anode ( 38 ) includes multiple target surfaces ( 36 ). Each of the target surfaces ( 36 ) has a focal spot that receives the electron beam ( 32 ). The target surfaces ( 36 ) generate multiple x-ray beams ( 42 ) in response to the electron beam ( 32 ). Each x-ray beam ( 42 ) is associated with one of the target surfaces ( 36 ). An x-ray imaging system ( 10 ) includes the cathode ( 30 ) and the anode ( 38 ). A controller ( 28 ) is electrically coupled to the cathode ( 30 ) and adjusts emission of the electron beam ( 32 ) on the anode ( 38 ).
