The algorithm iteratively optimises the position of 3D points. It eventually produces a point cloud, which needs to be voxelised to produce volume data that can be used with conventional medical image software. However, resulting voxel data is noisy. In our test case with 6,400 points the normalised cross-correlation (NCC) between the reference and the reconstruction is 85.53\%; with 25,600 points it is 93.60\%. This paper introduces a more robust 3D voxelisation method based on implicit modelling using metaballs to overcome this limitation. With metaballs, the NCC with 6,400 points increases up to 92.21\%; and up to 96.26\% with 25,600 points.}, pdf = {pdf/AliAbbood2015VCBM.pdf} }

Fully 3D tomographic reconstruction in PET requires high computing power and leads to many challenges. To date, the use of such methods is still restricted due to the heavy computing power needed. Evolutionary algorithms have proven to be efficient optimisation techniques in various domains. However the use of evolutionary computation in tomographic reconstruction has been largely overlooked. We propose a computer-based algorithm for fully 3D reconstruction in PET based on artificial evolution and evaluate its relevance.}, keywords = {Positron emission tomography, genetic algorithms, optimization methods}, doi = {10.1109/NSSMIC.2009.5401758}, publisher = {IEEE} }
