Firestone patented an instrument he called the Supersonic Reflectoscope, which is generally regarding as the first practical commercial ultrasonic flaw detector that used the pulse/echo technique commonly employed today. For example, if the object is 20 cm away from the sensor, and the speed of the sound is 340 m/s or 0.034 cm/µs the sound wave will need to travel about 588 microseconds. In the late 1940s, researchers in Japan pioneered the use of ultrasonic testing in medical diagnostics using early B-scan equipment that provided a two-dimensional profile image of tissue layers. /*]]>*/.
