| Popis: | This paper is regarding the literature study that has been conducted for the purpose of analyzing the ultrasonic images of gall bladder of the patients having abnormalities. In general most of the paper it has been found that in order to find abnormalities in gall bladder they consider the accumulation of stones. The study has been made clear that the densities, thickness of the stones, shape of the gall bladder are detected in most of the paper. Biological characteristics are given much importance than physical characteristics. A new approach is developed in this paper, that is gall bladder wall has to be considered in order to find the abnormality depending upon the thickness of the wall. Hence the Region of Interest is considered as wall of the gall bladder. The normal thickness of the wall of the gall bladder is less than 3mm. The pathogenesis in gall bladder is observed by the walls of the gall bladder as it gets enlarged in case if there is any abnormalities like presence of stones in the form of solid, liquid, or semi solid. Later on this physical characteristic like reflection coefficient, acoustic impedance and dynamic modulus are considered rather than biological characteristics and its mapped with the Region of Interest to find the changes and to analyse whether any intervention can be done in it. |
