Abstract:
:An iterative algorithm has been developed to reduce blur artefacts in images obtained from the Pho/Con multiplane tomographic scanner. In this technique estimates of the activity distribution are convolved with the detector response function and compared with the original blurred image planes. Successive estimates of the activity distribution are modified so as to minimise the square of the difference in pixel count between the two sets of blurred images. The technique has been tested with images containing non-correlated noise provided by computer simulation and images with correlated noise acquired in experimental phantom studies.
