Abstract
We have developed an algorithm for enhancement of spicules of spiculated masses,
which uses the discrete Radon Transform. Previously, we employed a commonly used
method to compute the discrete Radon transform, which we refer to as the DRT.
Recently, a new, more exact method to compute the discrete Radon Transform was
developed by Averbuch et al., which is called the Fast Slant Stack (FSS) method. Our
hypothesis was that this new formulation would help to improve our enhancement
algorithm. To test this idea, we conducted multiple 2-alternative-forced choice (2 AFC)
observer studies and found that most observers preferred the enhanced images generated
with the FSS method.
