Abstract
Diffraction and refraction effects on pulsed ultrasound were studied using simple models such as finger cots filled with saline or alcohol. The scattered ultrasound was detected with a hydrophone and A/D converter. The resulting set of digitized signals were analyzed for diffraction and refraction terms. Simple methods for backward propagating the received pressure field are described and results presented. The efficacy of diffraction tomography methods for solving the problems associated with transmission ultrasonic tomography is discussed.
