Abstract: An approach is disclosed for acquiring multi-sector computed tomography scan data. The approach includes activating an X-ray source during heartbeats of a patient to acquire projection data over a limited angular range for each heartbeat. The projection data acquired over the different is combined. An image having good temporal resolution is reconstructed using the combined projection data.

Abstract: An X-ray tube and methods for imaging are disclosed. The X-ray tube includes an emitter configured to generate an electron beam. Further, the X-ray tube includes a target configured to generate X-rays in response to the electron beam, where a target surface includes at least a first region having a first elevation and a second region having a second elevation different from the first elevation. The X-ray tube also includes a detector configured to generate projection data based on the X-rays and a computing device coupled to the emitter, the detector and/or the target. The computing device is configured to deflect a focal spot on the target surface by controlling target rotation such that the electron beam impinges alternatively on the first and second regions. The computing device processes the projection data corresponding to the deflected focal spot positions and reconstructs images of a subject using the processed projection data.
