Abstract :
The scanning laser acoustic microscopy (SLAM) technique offers high resolution for determining the properties of individual layers. To introduce the SLAM technique as a method for measuring the speed of sound in tubular layered organs, and possibly distinguish between the layers by this measure, the authors chose the guinea-pig urethra, due to its relatively simple layered structure. To obtain more data of the acoustic properties of tissue, the attenuation coefficient was determined for the wall in toto
