Local identification and removal of scatter artefacts based on the temporal information in dynamic SPECT images
Proceedings of the 17th International Conference on Pattern Recognition, 2004. ICPR 2004.
Scatter in SPECT images may mask decreseased uptake of radiopharmaceuticals in the left ventricle of the heart which can alter the diagnostic outcome of the study. The newly developed dynamic SPECT (dSPECT) method, which reconstructs 4D images from a standard acquisition protocol, provides additional temporal information which may be helpful to recognise such artefacts. Each voxel carries a time signature, which is different for different organs. In this paper, we investigate whether thisdoi:10.1109/icpr.2004.1334640 dblp:conf/icpr/TonniesPC04 fatcat:fez7smvegrgvnoxo7stkhetqte
