Abstract

In this paper is presented a nondestructive method to obtain and analyze ultrasound images of bone tissues by C-scan. By applying this method one can obtain bi-dimensional ultrasonic images in which the differences in the image contrast result from the ultrasound-bone tissue interaction. The experimental system consists in an ultrasound pulser-receiver IPR-100, a converter A/D-90 and a 3D transducer-displacement automated system equipped with step-by-step motors (SMC-4) provided by Physical Acoustic Corporation. Pulse-echo technique, in immersion, with a point-focused transducer H10MP15 supplied by Krautkramer Company is used here. Experiments were carried out on 3 human bone tissues samples of different ages. Analysis of C-scan images in amplitude and in TOF results in areal distribution maps of bone density. The number of surfaces and their size with different degrees of bone density are computed and compared..
