Simulation of Ultrasonic Fields and Echo Signals using Cross-Section Photograph of Test Object and FDTD Method

We present a simulation technique of ultrasonic fiel ds and echo signals, that uses a digitized crosssection photograph of a test object and a digitized cross -section figure of an ultrasonic probe as input data. The input data file is referred to as a shape file . In the shape file, different colors are assigned t o different materials, for example, red… CONTINUE READING
