Ultrasonic parameters of renal calculi and gall bladder stones as a function of density.
In this investigation, ultrasonic parameters of complex renal calculi and gall bladder stones, in vitro are measured using a double-probe contact by pulse-echo technique. Due to the variation in the chemical composition of the stones, a large variation in the value of ultrasonic parameters is found. A correlation between ultrasonic parameters and various renal calculi and gall bladder stone pathologies are also discussed. The ultrasonic parameters are found to vary as a function of density of the specimen used.
