Abstract: Technologies for computed tomography (CT) image reconstruction of moving objects include a computing device coupled to a CT scanner. The computing device captures sinogram data indicative of one or more moving objects and determines a trajectory for each object. The trajectory may be determined as a function of the sinogram data. To do so, the computing device may determine an enveloping curve from a set of intersections of sequential projections and identify a tangent line that touches the enveloping curve at two points. The computing device determines a trajectory sum as a function of the sinogram and the trajectory of each object. Determining the trajectory sum includes calculating a line integral along the trajectory in the sinogram space. The computing device may splice or interpolate combined sinogram data to generate sinogram data for each object. The computing device generates an image of each object based on the trajectory sum.
