Sentence examples for distribution of attenuation from inspiring English sources
The correction for photon attenuation requires the availability of patient-specific attenuation map, which accounts for the spatial distribution of attenuation coefficients of biological tissues.
The availability performance of the transmission link can be assessed from the cumulative distribution of attenuation due to all hydrometeors together for the known value of the fade margin.
These templates are based on CT transmission scans of the patient table or RF coils, providing an exact 3D representation of the spatial distribution of attenuation factors in a virtual model of the respective hardware component [24, 25].
Tissues have a unique distribution of attenuation values as a function of X-ray energy and spectral CT (dual-energy/multi-energy CT) can further distinguish them by exploiting their energy-dependent attenuation properties.
The solid line in Figure 6 corresponds to the CD of attenuation due to all the hydrometeors combined over the entire 6-year period of observation, and it may be considered as the long-term average annual distribution of attenuation due to all the hydrometeors combined in the sense of [10, 11].
CTTA assesses the distribution of attenuation values (heterogeneity) within a tumour or lesion.

Based on the appearance of lung morphology on CT, each patient was classified as having focal or non-focal distribution of attenuations [ 15].
The attenuation map is a distribution map of attenuation coefficients measured by CT and designed to obtain more legible PET images, thereby allowing PET and CT image fusion.
