Comparative assessment of different energy mapping methods for generation of 511-keV attenuation map from CT images in PET/CT sy
The use of X-ray CT images for CT-based attenuation correction (CTAC) of PET data results in the decrease of overall scanning time and creates a noise-free attenuation map (μmap)...
