The Real Time Tomography (RTT) system is a new type of fast cone beam CT scanner, using fixed rings of multiple sources and detectors in an offset geometry. We demonstrate the potential of this system for use in the imaging of high speed dynamic processes, such as moving fluid flows. The effect of the source firing pattern is discussed, with application to increasing the temporal resolution of the system. Through the use of a simple temporal regularisation term, we show that temporal resolution can be further increased, at the expense of a slight loss in spatial resolution.
