1. sound waves of a frequency greater than 20,000 Hz.
2. ultrasonography.
ul·tra·sound ( l tr -sound )n. Abbr. U/S 1. Ultrasonic sound. 2. The use of ultrasonic waves for diagnostic or therapeutic purposes, specifically to visualize an internal body structure, monitor a developing fetus, or generate localized deep heat to the tissues. |
Ultrasound
A non-invasive procedure based on changes in sound waves of a frequency that cannot be heard, but respond to changes in tissue composition. It requires no preparation and no radiation occurs. It has become the "gold standard" for diagnosis of stones in the gallbladder, but is less accurate in diagnosing stones in the bile ducts. Gallstones as small as 2 mm can be identified. The procedure can now also be done through an endoscope, greatly improving investigation of the bile ducts.

Etymology: L, ultra + sonus
sound waves at the very high frequency of over 20 kHz (vibrations per second). Ultrasound has many medical applications, including fetal monitoring, imaging of internal organs, and, at an extremely high frequency, the cleaning of dental and surgical instruments. ultrasonic, adj.
ultrasound,
n 1., a diagnostic radiology technique that uses sound waves to image internal body structures.
2., a machine that applies heat to injured tissue to relieve pain and encourage healing. Used in physical therapy and rehabilitation.

Patient discussion about Ultrasounds.
Q. Do doctors normally do ultrasounds to prove you have mis carried?? 2 weeks ago i found out i was pregnant, i started spottion so we went to the hospital where they toldl me i miscarried, but they did not do any alternative tests to prove it not even check my Hcg levels. Im wandering if i should get a second opinion to make sure.
A. Congratulations on the new pregnancy - that's wonderful news!
Q. what kind of uses the medicine do with computers related to ultra sound? how does the computer helps the doctors in the ultra sound? what do the compuers use for?
A. the computers help the doctors (in ultrasound cases) to interpret/convert the ultrasound waves into a specific imaging showed in the monitor. by that a doctor can find what is normal or not inside the patient's body.
for pregnancy purposes, it really helps patient in antenatal screening to find some abnormalities (if there's any) and to monitor the fetus' development along the 9-months pregnancy.

Q. Can anyone suggest a treatment for plantar fasciitis, apart from ultrasound, physio, anti-inflammatory agents? My friend has had Plantar Fasciitis for more than 1 year and has persevered with all the ususal treatments above plus lots of rest from weight-bearing and elevation.
A. Padded foot splints, silicone heels insert and special shoes (e.g. arch-supporting shoes) may also help. These are usually sold and fitted by a professional. Exercise is another important measure. Some patients benefit from avoiding walking barefoot or in sleepers but rather using shoes from the first step.
More advanced treatments include steroid-local anesthetics injections, botulinum toxin (similar to botox) injections and surgery.
The prognosis is usually favorable, and most patients achieve relief of the pain.
However, all of the above is just for general knowledge - if you have any specific question, you may want to consult a doctor.
