3D ultrasound is a medical ultrasound technique, often used in fetal, cardiac, trans-rectal and intra-vascular applications. 3D ultrasound refers specifically to the volume rendering of ultrasound data. When involving a series of 3D volumes collected over time, it can also be referred to as 4D ultrasound (three spatial dimensions plus one time ...
Although early studies on 3D imaging were begun in Japan by Kazunon Baba in 1984, it was not until the production of the third generation 530D Voluson in the mid 1990’s that the world was convinced that 3D/4D ultrasound had a major role to play in both obstetrical and gynaecological imaging.
Ultrasound technology, also known as sonography, had its origins in the early 20th century. The groundwork was laid by physicist Paul Langevin during World War I, who used high-frequency sound waves to detect submarines underwater.
Starting in the 1980s, ultrasound technology became more sophisticated with improved image quality and 3D imaging capabilities. These improvements continued into the 1990s with the adoption of 4D (real time) capabilities. Ultrasound guided biopsies (endoscopic ultrasounds) also began in the 1990s. 2000s – present
Ultrasound was first used for clinical purposes in 1956 in Glasgow. Obstetrician Ian Donald and engineer Tom Brown developed the first prototype systems based on an instrument used to detect...
With improvements in ultrasonic and computer technology, work on three-dimensional visualization began to appear in the early 1980's. Some basic computer algorithms came from the group at Stanford (JF Brinkley, WD McCallum and others) and also from the Holm group at Gentofte, Denmark.
In this article, previous and the latest work on designing a real-time or near real-time 3D ultrasound imaging system are reviewed. Specifically, the data acquisition techniques, reconstruction algorithms, volume rendering methods, and clinical applications are presented.
