摘要: Methods and apparatus for x-ray imaging with focal spot deflection are provided. The apparatus includes an x-ray tube having a cathode configured to emit electrons and an anode having a target with a target surface defining a target angle. The emitted electrons are deflected onto the target surface with the target surface substantially aligned with a z-axis parallel to a gantry rotation axis.
