Device-less gating for pet/ct using pca
WebDec 14, 2012 · Purpose Respiratory gating is an established approach to overcoming respiration-induced image artefacts in PET. Of special interest in this respect are raw PET data-driven gating methods which do not require additional hardware to acquire respiratory signals during the scan. However, these methods rely heavily on the quality of the … WebDec 6, 2024 · The application of principal component analysis (PCA)-based DDG algorithm improves both image quality and quantitative SUVs in subcentimeter lesions measuring above 6 mm, and although DDG application cannot detect new subCentimeter lesions, it increases the visual indices. Introduction. The application of data-driven respiratory …
