METHOD OF DETERMINING ECHOHOMOGENITY AND ECHOGENITY DEGREE OF ULTRASONIC IMAGE Russian patent published in 2010 - IPC A61B8/00 A61B8/14 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to X-ray diagnostics and is intended for determination of echohomogeneity and echogenicity degree of ultrasonic image. Two zones, located at the same distance from sensor - examines zone and background zone - are compared. For this purpose, on ultrasonic image compared zones are highlighted and using function 'brightness histogram" numerical values of parametres "mean value" and "deviation" for compared zones and "deviation" for sections of background zone are obtained. After that calculated are difference of mean values of brightness of examined and background zones, deviation error in background zone, criterion of examined zone echohomogeneity (CEH), criterion of isoechogenecity (CES) for echohomogenous examined zone. All criteria are calculated by certain formulas. Echohomogeneity and echogenecity degree are calculated on the basis of obtained calculated values of said parametres.

EFFECT: method allows to determine in a reliable way echohomogeneity and echogenecity degree obtained during ultrasonic examination of changes and lesions.
