Abstract
An experimental method for evaluating the performance of capacitance t omographic flow imaging systems is described. Criteria are defined to describe the performance of these systems, namely spatial and permitti vity resolution, accuracy (system errors) and signal to noise ratio. S tatic physical models simulating typical flow distribution patterns ar e used as standard test objects and the criteria are quantified by com paring the reconstructed images with the standards. Systems with 8 and 12 electrodes have been tested and the results compared to show the i mprovement obtained with the increased number of electrodes.
