The Physics of Ultrasounds Essay

A shadow picture is constructed from different echoes being reflected from a variety of tissues (Radiological Society of North America). Ultrasounds can come in many forms. Traditional images are displayed in thin, flat sections of the body. However, advancement in technology now includes 3-D and 4-D ultrasounds as well as many other specific types (Radiological Society of North America).

* Ultrasound. An ultrasound uses high-frequency sound waves to generate images of your internal organs, such as your kidneys and bladder, on a computer screen.

Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

Sonography is a non-invasive medical procedure that uses the echoes of high-frequency sound waves to construct an image of internal organs or body structures. The employment rate is is expected to grow 26 percent from 2014 to 2024. Since ultrasound is non-invasive, it is more encouraged than other methods so the career is always in demand. Diagnostic medical sonographers duties are to prepare and maintain diagnostic imaging equipment, taking a patients medical history, answering questions about the procedure, operating the equipment, review images and test results, know the difference between normal and abnormal images, analyze diagnostic information, record findings, and keep track of patient records. Hospitals, offices of physicians, medical

Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies

Ultrasonic sensors emit short, high-frequency sound pulses at regular intervals. These propagate in the air at the velocity of sound. If they strike an object, then they are reflected back as echo signals to the sensor, which itself computes the distance to the target based on the time-span between emitting the signal and receiving the echo.

Sonography utilizes sound waves to generate an image that can be analyzed to determine or rule out a diagnosis. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. A diagnostic medical sonographer works directly with patients in a dimly lit room with imaging machines. The sonographer gets the medical history of the patient and prepares the patient for an ultrasound examination. The sonographer explains the noninvasive procedure and answers any question the patient might have. The sonographer positions the patient and covers the patient only exposing the area needed for the procedure. The sonographer

During a pregnancy, many expecting mothers will travel to the doctor to have a check up with how the pregnancy is doing. Many mothers will get done a special procedure that is called an ultrasound. An ultrasound 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 the placenta.(2-1) Ultrasounds may be performed at any point during a pregnancy, and the results are seen immediately on a monitor during the procedure.(2-2) The ultrasound doesn’t hurt the mother or the fetus. There are many situations where ultrasounds can be used. Some doctors will use an ultrasound to look at someone’s abdomen, especially if there is stomach pains and nausea present. One

Ultrasound relies on high frequency sounds to image the body and diagnose patients. Ultrasounds are therefore longitudinal waves which cause particles to oscillate back and forth and produce a series of compressions and rarefactions

A Sonographer operates ultrasound equipment which is a scanning technology which uses sound waves to create images of soft and hard tissues. Mainly known for performing fetal and pregnancy inspections and check-ups, the technology has been adapted to performing diagnostics of practically every part of the human body (Szabo, 2004). Today ultrasound has grown into a powerful medical screening tool which medical professionals turn to for accurate internal imaging to determine the extent of the patient’s conditions.

Ultrasound, i.e. sound waves of frequency higher than 15-20 kHz, can cause inactivation of cell; besides ultrasound at

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
