The study of the B-mode Ultrasonic Scanner
Douglas Howry and Joseph Holmes, from the University of Colorado. Where the trailblazers of "B-mode" ultrasound equipment, including the 2-D B-mode linear compound scanner. A B-mode ultrasound is a "ray of transducers simultaneously scans a plane through the body that can be viewed as a two-dimensional image on screen". -
Ian Donald
Ultrasound was first used for medical purposes. Glasgow was the place where it saw its first light. Besides, ultrasound was the brainchild of engineer Tom Brown and Obstetrician Ian Donald. They were the first people who crafted the prototype system. -
Ian Donald ( A-mode)
Introduced the ultrasound in diagnostic and medicine in 1956, when he used the one-dimensional A-mode (amplitude mode) to measure the parietal diameter of the fetal head. -
Ian Donald /OBGYN
Donald incorporated ultrasound into the OBGYN field of medicine. The ultrasound image of a female genital tumor. Dr. Tom Brown invented the so-called “two-dimensional compound scanner”, which enabled the examiner to visualize the density of the tissue. -
The Grey Scale
the “grey scale” was introduced Kossoff, Garrett leading to the introduction of the real-time ultrasound scanners. A grey scale typically renders a two-dimensional image in which the organs and tissue of interest are depicted as points of variable brightness. -
Pulsed Doppler Ultrasound
Don Baker, Dennis Watkins, and John Reid designed pulsed Doppler ultrasound technology. Doppler uses the Doppler principle that moving objects change the characteristics of sound waves. By sending short and quick pulses of sound, it becomes possible to accurately measure the velocity of blood in a precise location and in real time. -
Developments of the Wave Doppler
Many developments including the continuous wave Doppler -aw many, spectral wave Doppler and color Doppler ultrasound instruments. -
Ultrasound Tech.
Ultrasound technology became more sophisticated with improved image quality and 3D imaging capabilities. -
3D Ultrasound Tech.
Kazunori Baba of the University of Tokyo developed 3D ultrasound technology and captured three-dimensional images of a fetus in 1986. -
Lung and General Sonography
Professor Daniel Lichtenstein began incorporating lung and general sonography in intensive care units. Which is basically a chest ultrasound is a noninvasive diagnostic exam that produces images, which is used to assess the organs and structures within the chest, such as the lungs. -
4D Tech.
the adoption of 4D (real time) capabilities. Ultrasound guided biopsies (endoscopic ultrasounds) also began in the 1990s. Similar to a 3D ultrasound, except it displays the images of the baby in a live-streaming video. -
Present Day Ultrasound
Just like personal communication devices are continuously evolving and becoming more convenient, so are ultrasound technologies. A variety of compact, handheld devices have come onto the market in recent years.
