Ultrasound has been used by radiologists and sonographers to image the human body for at least 50 years and has become a widely used diagnostic tool. [36] The technology is relatively inexpensive and portable, especially when compared with other techniques, such as magnetic resonance imaging (MRI) and computed tomography (CT).
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
The ADR 2130, designed by Marty Wilcox was the first portable ultrasound unit commercially available in the United States, being released in 1975. This unit weighed about 25 lbs, had 3 linear probes to choose from and used an oscilloscope for a display instead of a TV monitor. [ 1 ]

Diagnostic medical sonography (DMS), a branch of diagnostic medical imaging, is the use of imaging by medical ultrasound for medical diagnosis. DMS uses non-ionizing ultrasound to produce 2D and 3D images of the body. In Canada, the credentialing for diagnostic medical sonography is the Canadian Association of Registered Ultrasound Professionals.
Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
The above video is certainly not conclusive evidence of widespread ilcliteracy — but you don’t have to look especially hard to find it. Whether listening to a popular song, watching a television show, seeing a film or reading a magazine, the totality of human sexual pleasure is often reduced to a penis penetrating a vagina.
The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s. [1] On May 27, 1940, U.S. researcher Dr. Floyd Firestone of the University of Michigan applies for a U.S. invention patent for the first practical ultrasonic testing method.
