Association between power law coefficients of the anatomical noise power spectrum and lesion detectability in breast imaging modalities

摘要

PurposePrevious research has demonstrated that a parameter extracted from a power function fit to the anatomical noise power spectrum, β, may be predictive of breast mass lesion detectability in x-ray based medical images of the breast. In this investigation, the value of β was compared with a number of other more widely used parameters, in order to determine the relationship between β and these other parameters.
