• 3D ultrasound - Wikipedia, the free encyclopedia: 3D ultrasound is a medical ultrasound technique used during pregnancy, providing three dimensional images of the fetus. Often these images are captured rapidly and animated to produce a "4D ultrasound&quo t;. There are several different scanning modes in medical and obstetric ultrasound. The standard common obstetric diagnostic mode is 2D scanning.[1] In 3D fetal scanning, however, instead of the sound waves being sent straight down and reflected back, they are sent at different angles. The returning echoes are processed by a sophisticated computer program resulting in a reconstructed three dimensional volume image of fetus's surface or internal organs; allowing one to see width, height and depth of images in much the same way as 3D movies but no movement is shown. 3D ultrasound was first developed by Olaf von Ramm and Stephen Smith at Duke University in 1987.[
• Medical ultrasonograph y - Wikipedia, the free encyclopedia: Medical sonography (ultrasonograp hy) is an ultrasound-bas ed diagnostic imaging technique used to visualize muscles and internal organs, their size, structures and possible pathologies or lesions. Obstetric sonography is commonly used during pregnancy and is widely recognized by the public. There are a plethora of diagnostic and therapeutic applications practiced in medicine. In physics the term "ultrasou nd" applies to all acoustic energy with a frequency above human hearing (20,000 hertz or 20 kilohertz). Typical diagnostic sonographic scanners operate in the frequency range of 2 to 18 megahertz, hundreds of times greater than the limit of human hearing. The choice of frequency is a trade-off between spatial resolution of the image and imaging depth: lower frequencies produce less resolution but image deeper into the body.
