Abstract

The University of Birmingham has pioneered the use of positron imaging for the study of granular, liquid and multi-phase flows. We have acquired a number of redundant hospital PET scanners, which have been reconfigured to best suit engineering requirements. A significant step towards realizing optimal particle tracking comes from understanding camera performance. Count rate studies for our detectors have been performed and compared to theoretical models. Experimental and Monte Carlo data are used to optimise the design of detector geometries for specific applications. The implications for the next generation of positron camera for industrial PEPT are discussed.
