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.
By changing the pulse delays, the computer can scan the beam of ultrasound in a raster pattern across the tissue. Echoes reflected by different density tissue, received by the transducers, build up an image of the underlying structures. Weld examination by phased array. TOP: The phased array probe emits a series of beams to flood the weld with ...
Technicians who use ultrasound to examine the heart chambers, valves, and vessels are referred to as cardiac sonographers. [1] They use ultrasound instrumentation to create images called echocardiograms. An echocardiogram may be performed while the patient is either resting or physically active. Technicians may administer medication to ...
The AIUM's membership consists of more than 10,000 sonographers, physicians, scientists, engineers, other health care providers, manufacturers of ultrasound equipment, and students. The AIUM is directed by a Board of governors and Executive Committee who are assisted by committees and a Council on Sections, representing many ultrasound ...
Historically, Ultrasound, Nuclear Medicine and Cardiology Cath Labs are often departments that adopt such an approach. More recently, Full Field digital mammography (FFDM) has taken a similar approach, largely because of the large image size, highly specialized reading workflow and display requirements, and intervention by regulators.
Reflected ultrasound comes from an interface, such as the back wall of the object or from an imperfection within the object. The diagnostic machine displays these results in the form of a signal with an amplitude representing the intensity of the reflection and the distance, representing the arrival time of the reflection.
The article contained the first published ultrasound image of a fetus. [21] The development of Donald's interest in ultrasound started when one of his patients introduced her husband to him. The patient's husband was the director of the boiler fabrication company Babcock and Wilcox, and he offered a tour of the plant to Donald, who accepted. [4]
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging , using standard ultrasound or Doppler ultrasound . [ 1 ] The visual image formed using this technique is called an echocardiogram , a cardiac echo , or simply an echo .
