Abstract: We describe a technique for discriminating between livers that are normal and ones that have fatty infiltrate (livers with steatosis) based upon the application of a suitably defined texture measure to the corresponding digitized ultrasonographs. In brief, this texture measure sums, from some selected optimum spatial frequency to the upper limit set by the digitizing process, the frequency components of the normalized, radial power spectral density function. The analysis was run on six cases (two normal and four with steatosis) obtained from Dunedin Public Hospital, in New Zealand. Texture measure values for these six cases were compared with the corresponding biopsy scores. The results indicate the ability of the texture measure to discriminate between the two conditions; and furthermore, to quantitatively distinguish the severity of histology change.
