A method for evaluating and comparing the performance of benchmark gamma-ray imaging instruments is proposed and demonstrated. This method makes simplifying assumptions that do impact the accuracy of performance estimation and the range of conditions under which performance estimation will be reliable. However, the method provides a valuable means for evaluating imager performance under many conditions of relevance for detection applications, and provides an upper bound for performance that is valid under all conditions. This estimate enables, for the first time, a meaningful means for comparing imaging instruments against one another and for making rapid determinations of the potential viability of using specified imaging instruments for detection application scenarios. The insight provided by this model should also motivate future innovation in imager design.
