Preferred Label : Attenuation Correction;
NCIt related terms : Attenuation Correction Type; ATTCRCT;
NCIt definition : Adjustment for the effect of tissue thicknesses through which gamma's travel from
an activity concentration origin to the scanner's detectors. The count rates of a
detector are adjusted to values as if there were no attenuation along the gamma's
path. This makes possible accurate quantitation in image analysis.;
Alternative definition : CDISC: The adjustment for the effect of tissue thicknesses through which gamma's travel
from an activity concentration origin to the scanner's detectors. The count rates
of a detector are adjusted to values as if there were no attenuation along the gamma's
path. This makes possible accurate quantitation in image analysis. (NCI);
