Ultrasonic parenchymal textures can be considered as an hystological macrostructure of an organ, modified by the acoustic pulse-tissue interaction and various performances factors of the instrument. We have already demonstrated that a multiple holographic filtering proves satisfactory for recognition and classification of liver echostructures.

Abstract
Ultrasonic parenchymal textures can be considered as an hystological macrostructure of an organ, modified by the acoustic pulse-tissue interaction and various performances factors of the instrument. We have already demonstrated that a multiple holographic filtering proves satisfactory for recognition and classification of liver echostructures. In this paper we present another coherent optical correlation method based on the Joint Fourier Transform (JFT)File in questo prodotto:
