What are Obstetric Ultrasound Scans?
Obstetric Ultrasound is the use of ultrasound scans in pregnancy. Since its introduction in the late 1950’s ultrasonography has become a very useful diagnostic tool in Obstetrics. Currently used equipments are known as real-time scanners , with which a continous picture of the moving fetus can be depicted on a monitor screen. Very high frequency sound waves of between 3.5 to 7.0 megahertz (i.e. 3.5 to 7 million cycles per second) are generally used for this purpose. They are emitted from a transducer which is placed in contact with the maternal abdomen, and is moved to "look at" (likened to a light shined from a torch) any particular content of the uterus. Repetitive arrays of ultrasound beams scan the fetus in thin slices and are reflected back onto the same transducer. The information obtained from different reflections are recomposed back into a picture on the monitor screen (a sonogram, or ultrasonogram). Movements such as fetal heart beat and malformations in the feus can be assessed and measurements can be made accurately on the images displayed on the screen. Such measurements form the cornerstone in the assessment of gestational age, size and growth in the fetus.

From Wikipedia, the free encyclopedia
Jump to: navigation search For other uses, see Ultrasound (disambiguation) Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing . Although this limit varies from person to person, it is approximately 25 kilohertz (25,000 hertz) in healthy, young adults and thus, 25kHz serves as a useful lower limit in describing ultrasound. Ultrasound is manually produced in many different fields, typically to penetrate a medium and measure the reflection signature or supply focused energy. The reflection signature can reveal details about the inner structure of the medium. The most well known application of this technique is its use in sonography to produce pictures of fetuses in the human womb. There are a vast number of other applications as well.

The upper frequency limit in humans (approximately 20 kHz) is caused by the middle ear , which acts as a low-pass filter . If ultrasound is fed directly into the skull bone and reaches the cochlea without passing through the middle ear, much higher frequencies can be heard. This effect is discussed in

What if the ultrasound shows a problem? What is an ultrasound? An ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements.

Email An ultrasound exam is a procedure that uses high-frequency sound waves to scan a woman's abdomen and pelvic cavity, creating a picture (sonogram) of the baby and placenta. Although the terms ultrasound and sonogram are technically different, they are used interchangeably and reference the same exam.
What types of ultrasound are there?
There are basically seven different ultrasound exams, but the principle process is the same. The different types of procedures include:
Transvaginal Scans: Specially designed probe transducers are used inside the vagina to generate sonogram images. Most often used during the early stages of pregnancy.
Standard Ultrasound: Traditional ultrasound exam which uses a transducer over the abdomen to generate 2-D images of the developing fetus .
Advanced Ultrasound: This exam is similar to the standard ultrasound, but the exam targets a suspected problem and uses more sophisticated equipment.

What is an ultrasound?
An ultrasound test is a radiology technique, which uses high- frequency sound waves to produce images of the organs and structures of the body. The sound waves are sent through body tissues with a device called a transducer. The transducer is placed directly on top of the skin, which has a gel applied to the surface. The sound waves that are sent by the transducer through the body are then reflected by internal structures as "echoes." These echoes return to the transducer and are transmitted electrically onto a viewing monitor. The echo images are then recorded on a plane film and can also be recorded on videotape. After the ultrasound, the gel is easily wiped off. The technical term for ultrasound testing and recording is "sonography." Ultrasound testing is painless and harmless. Ultrasound tests involve no radiation and studies have not revealed any adverse effects.

World of the Body: ultrasound fetus in early pregnancy , but there are also many other diagnostic applications. Treatment by ultrasound ( ultrasonics ) is widely used by physiotherapists, particularly for soft tissue injuries but also for a variety of more chronic conditions, with a view to promoting healing and relieving pain. Most commonly frequencies of 1-3 MHz are used. There are differences of opinion and practice, related to whether the intended action should be primarily thermal or non-thermal, but there is a lack of controlled trials on the efficacy of the different methods used. See imaging techniques sonogram Food and Fitness: ultrasound Very high frequencies of sound, above 20 kHz. Ultrasound is used in both diagnosis and treatment. Ultrasonography uses echoes of the sound waves to produce images of structures within the body. Continuous ultrasound is a common treatment for deep, soft-tissue injuries. The high-frequency sound waves are believed to vibrate and loosen scar tissue, accelerating the healing process. The vibrations also heat deep tissues and relieve pain. If a swelling occurs, pulsed ultrasound is used because, unlike continuous ultrasound, it does not heat up the tissues. Ultrasound may also be used in a process called phonophoresis to drive anti-inflammatory drugs through the skin into underlying tissue.

Ultrasound imaging (also called ultrasound scanning or sonography) is a relatively inexpensive, fast and radiation-free imaging modality. Ultrasound is excellent for non-invasively imaging and diagnosing a number of organs and conditions, without x-ray radiation. Modern obstetric medicine (for guiding pregnancy and child birth) relies heavily on ultrasound to provide detailed images of the fetus and uterus. Ultrasound can show fetal development, and bodily function like breathing, urination, and movement. Ultrasound is also extensively used for evaluating the kidneys, liver, pancreas, heart, and blood vessels of the neck and abdomen. Ultrasound can also be used to guide fine needle, tissue biopsy to facilitate sampling cells from an organ for lab testing (for example, to test for cancerous tissue).

    Quick Reference: Fact Sheets Ultrasound
    Ultrasound is a technique that uses sound waves to show a picture of a baby (fetus) in the uterus. Because it uses sound waves instead of radiation, ultrasound is safer than X-rays. Ultrasound provides important information about the health of the fetus and conditions in the uterus. This information can guide a health care provider’s plans for a pregnant woman and improve the outcome of pregnancy. How does ultrasound work?
    Ultrasound works by bouncing sound waves off the developing fetus. Echoes from the waves are analyzed by computer to produce a moving or still picture, called a sonogram, on a screen. The technique is also called sonography. How is ultrasound performed?
    Two common forms of ultrasound used in pregnancy are:
    • Transabdominal Transvaginal
    In a transabdominal ultrasound exam, the health care provider or medical technician moves a handheld device, called a transducer, along the pregnant woman's abdomen. The transducer sends sound waves into the woman’s uterus and also detects the echoes from those waves, which it then converts into electrical signals. The computer then assembles these signals into a picture. To get a clearer picture, the provider or technician covers the woman’s abdomen with a thin layer of gel, which helps improve the transmission of sound waves. The woman also may be asked to have a full bladder during the test. The exam is painless, but many women find having a full bladder uncomfortable.

    What Is An Ultrasound?
    Ultrasound is a procedure that uses high-frequency sound waves to view internal organs and produce images of the human body. The human ear cannot hear the sound waves used in an ultrasound. Ultrasound is:
    • Noninvasive, which means it does not penetrate the skin or body openings, and Diagnostic, which means it is used to determine what disease or condition is present
    The technical term for ultrasound imaging is sonography. Ultrasound technology was originally developed as sonar to track submarines during World War I. It was first used medically in the 1950s and is considered very safe. The original ultrasound scanners produced still images, but modern scanners produce moving pictures, which are easier to interpret. Back to Top of Page Next To continue, select a heading below:
