Segmenting contrast-enhanced CT images for attenuation correction of PET/CT data
The use of contrast media in positron emission tomography (PET)/computed tomography (CT) dual modality imaging has been shown to cause artifacts in the PET image. These artifacts are attributed to an overestimation of the ...
Approaches for respiratory motion compensation in positron emission tomography imaging
Respiratory patient motion often causes image blur and inaccurate quantitation results in positron emission tomography (PET) imaging. Traditional gated acquisition approach corrects motion artifacts by generating a snapshot ...
