A method for Computed Tomography (CT) imaging is provided. The method comprises rotating a gantry at a substantially slow rotation speed about a volume of interest. The gantry comprises a combination of X-ray source points. The X-ray source points comprise one or more discrete emission points and an arc of discrete or continuous X-ray source points. The method then comprises obtaining projection data from the combination of X-ray source points and performing a suitable reconstruction based on the projection data obtained from the combination of X-ray source points, to generate one or more reconstructed images.
