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).
During his training, he worked with Ian Donald, who had published some of the first papers on the use of ultrasound in obstetrics. Together, they published multiple papers on fetal biometry and developed charts of fetal measurements, such as the biparietal diameter and head circumference. Their collaboration led to methods for estimating fetal ...
The first Outreach course took place in Manila, the Philippines, in 1996. Outreach is committed to improving maternal healthcare services in underserved regions of the world by: Promoting and providing high-quality education in ultrasound in obstetrics and gynecology; Improving the availability of ultrasound
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.
Ian Donald CBE FRFPSGlas FRCOG FRCP (27 December 1910 – 19 June 1987) was an English physician who pioneered the diagnostic use of ultrasound in obstetrics, enabling the visual discovery of abnormalities during pregnancy. [2]
One healthcare professional in Louisiana faced this dilemma midway through her medical residency and ultimately left the state to pursue an OB-GYN practice where abortions are permitted.
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...
