Abstract:
Degraded ECT images can be improved through the application of image enhancement techniques. In this paper, three different image enhancement techniques--simple smoothing, 2-dimensional filtering and 1-dimensional filtering of the projection data-are implemented and evaluated for a phantom study. Cross-sectional images of the phantom are reconstructed from the modified projection sets. A goal of producing clearer and more useful images is achieved to varying degrees for each technique. The effects produced by modifying the parameters of the 1-dimensional filter are also investigated.
