Abstract :
Accuracy and precision were experimentally evaluated for the scanning laser acoustic microscope (SLAM) by measurements on homogeneous liquids of known ultrasonic properties. Using aqueous solutions of bovine serum albumin, the attenuation coefficient accuracy and precision are +or-12% and +or-15%, respectively. Using Dow Corning 710, a silicone oil, the speed accuracy and precision are +or-2.9% and +or-0.4%, respectively. Precision was assessed using duplicate samples of canine skin and wound tissue. The estimated precisions in the measurement of the attenuation coefficient and speed were +or-16% and +or-1.7%, respectively.<>
