ABSTRACT: Ultrasonic parameters such as ultrasonic velocity, acoustic
impedance, attenuation, dynamic modulus of elasticity, coefficient of
reflectance and transmittance have been determined for several renal
calculi samples, in vitro. These parameters are studied by using a
single probe method (pulse echo) in liquid form at different
concentrations (gm/cc). It was found that as the concentration
increases, the ultrasonic velocity increases. A pulse receiver (model
Panametries-5052 PR) was used to excite the transducer (2.5 MHz) and the
output was given to CRO (model-OS-300C, 20 MHz). A sample holder
assembly was used in the present work. The authors have also determined
all acoustic parameter mentioned above by using a double-probe
through-transmission method for several renal calculi samples in the
solid rock form. The present study would help in determining the design
parameters to design and develop a simple kidney stone
