Abstract: An imaging system includes a detector configured to obtain radiation data from one or more sources and a controller. The controller is configured to define plurality of buffers based on at least one initial condition. The radiation data includes a plurality of events. The controller is configured to receive an individual event of the plurality of events and determine if the individual event falls within a designated current buffer. Each of the plurality of events in the current buffer is corrected for pose and aligned in a common two-dimensional space. The plurality of events in the current buffer are reconstructed into a three-dimensional space, the reconstruction being done once for each of the plurality of buffers. The controller is configured to create a three-dimensional image based in part on the reconstruction in the three-dimensional space.
