A quantitative assessment of structural errors in grid maps
Various common error sources affect the quality of a map, e.g., salt and pepper noise and other forms of noise that are more or less uniformly distributed over the map. But there ...

Using recursive spectral registrations to determine brokenness as measure of structural map errors
—There are many common error sources that influence mapping, e.g., salt and pepper noise as well as other effects occurring quite uniformly distributed over the map. On the oth...

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)...
