Abstract: The article discusses the significance of ultrasound which generates visual images from inside the human body like the fetus, malignant tissue and other diagnosis from the test medium. Ultrasound is based on a wave-material interactive phenomena which determines material characteristics such as density, thickness, mechanical properties and level sensing. Ultrasound provides a nondestructive characterization of materials and noninvasive diagnostics applications in the medical field.
