Ultrasound transmission and reflection computerized tomography for imaging bones and adjoining soft tissues

Abstract

An ultrasonic imaging system that simultaneously collects attenuation, time of flight, and backscatter data from multiple views to make tomographic images is described. By using 80 such cross sections, three-dimensional images of turkey and dog limbs are constructed. The images are of high quality and provide detailed information on geometry and nature of structures that constitute bone and surrounding soft tissue. They reveal topological information of regions of interest without shadow and artifacts, and thus provide a distinct advantage over conventional single-line methods for measuring tissue properties.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
