Abstract
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).
