By creating an xray using sound waves.
Ultra sound is a technique used to detect things which are unreachable as in the case of finding water bodies under the earths surface or the development of fetus in a mother's womb.
Ultrasound is essentially a form of sonar. You bounce sound waves off of things and by observing the reflection, you can form a picture of things that are hidden from view.
An imaging ultrasound is a simple, safe and routine procedure using very high frequency (ultrasonic) sound waves to "look inside" the body. In the exam room the sonographer will apply a gel to 1) aid in the conduction of the ultrasonic signal from the wand to the skin and 2) lubricate the skin to make it easier to slide the probe around. The ultrasonic probe will be placed on the skin and slid around while the sonographer looks at imaging results. Maneuvering the probe permits different "views" of a given area of interest. The interpretation of the displayed images is the real meat and potatoes of sonography. It's all about interpreting the results. A more experienced sonographer usually delivers a better interpretation or "reading" of the ultrasound. Because the procedure is non-invasive and quite benign, it is a slam dunk for many evaluations. Though there are limitations, ultrasounds ability to "see" the forms that soft tissue takes makes it a superb tool for things like prenatal checkups.

An ultrasound imaging device sends ultrasound waves into the body. Then
it detects the reflected sound waves. Different parts of the body, such as bones, muscles, the liver, or the heart, reflect sound
differently. ;).
Ultrasound is applied directly on
the skin of the patient using a
wand that is round headed. You
need to apply ultrasound gel on
the surface where the physical
therapy has to be done in order to reduce the friction on the
skin due to ultrasonic waves.
Generally, the frequency of the
therapeutic ultrasound in
physical therapy is in the range
of around 0.8-1.0 MHz. The ultrasonic waves are generated
due to the piezoelectric effect
caused by the crystals which
vibrate in the head of the
ultrasound wand. Ultrasound in physical therapy is
brought about by a set of
sound-waves which are produced
in the ultrasound wand. These
sound waves are then passed to
the affected area through your skin causing vibration to the
tissues. These vibrations produce
heat to the effected area but
the patient may not feel the
heat. Apart from the likely
heating effect that is produced by the ultrasound, there are
some other known effects as
well. The use of ultrasound in
physical therapy helps in the
relaxation of the tissues. They
break down the tissues on the scar and generate blood flow to
areas where it was previously
blocked.
An ultrasound machine sends sound waves into an object. Those sound waves bounce off of things inside the object hence creating a little image of what is there. When the waves come back they display an image on the screen.
A Doppler ultrasound sends sound waves through the body and it 'echos' off the insides of your body to produce the images that you normally would see on an ultrasound.
One can find a guide on how an ultrasound works by visiting the website How It Works. At this website, one can get a step by step description of how the ultrasound operates, including the scientific principles.
Precautions.Clear scrotal ultrasound images are difficult to obtain if a patient is unable to remain still. It is not invasive and involves no radiation.
Sonographers use ultrasound sonography to produce such images. "Ultrasound" refers to sound waves with frequencies (pitch) above the range of human hearing. The system works by emitting sound waves and detecting them when they are reflected back. This is analogous to the process of viewing an object illuminated by a flashlight; light and sound are both waves and can be detected with the appropriate instruments.
Ultrasound.
NO an abdominal sonogram/ultrasound will not cause youto urinate blood. If you had that symptom before it was caused by something other than the ultrasound. An ultrasound is a test using high frequency sound waves to take images of your internal organs
An ultrasound technician uses an ultrasound machine to product images of tissues and organs. An ultrasound machine includes transducer probe, a central processing unit, a monitor, a keyboard with control knobs, disk storage devices and a printer.
Pop Art created using the images of ultrasound scans is known as ultrasound pop art. The images of unborn babies are usually scanned, and then converted into art portraits, creating the first and only portrait of the unborn. These make for great baby shower gifts too and are fast gaining popularity with parents to be.
Three-dimensional ultrasounds provide detailed images of fetuses in the uterus
an ultrasound
The answer will depend on where in the world she or he works.
Ultrasound technicians use medical equipment that send high-frequency sound waves through a patients body to create images, pictures and videotapes.
In some cases a radiologist will watch the ultrasound being accomplished, but in most cases the technician actually does the ultrasound. The radiologist simply reads the completed ultrasound and views the pictures (images) and video if available.
