Ultrasound application allows for noninvasive visualization of tissue structures. Real-time ultrasound images are integrated images resulting from reflection of organ surfaces and scattering within heterogeneous tissues. Ultrasound scanning is an interactive procedure involving the operator, patient, and ultrasound instruments.

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" audible sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz 20, hertz in healthy young adults. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws.
An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. It is suitable for use during pregnancy. Ultrasound scans, or sonography, are safe because they use sound waves or echoes to make an image, instead of radiation. Ultrasound scans are used to evaluate fetal development, and they can detect problems in the liver, heart, kidney, or abdomen. They may also assist in performing certain types of biopsy. The person who performs an ultrasound scan is called a sonographer, but the images are interpreted by radiologists, cardiologists, or other specialists.
Ultrasonography is a highly operator dependent imaging modality with a number of knobology variables that are under the control of the operator. Knobology is a terminology that describes the manipulation of ultrasound knobs and system controls in order to obtain the best image possible from diagnostic ultrasound. The inadequate use of knobology variables may impair image quality and can result in misdiagnosis. In abdominal sonography, selecting the appropriate application preset for abdominal examination is first step towards achieving an optimum image. The next step is to select an appropriate transducer frequency which must take the size of the patient into account.

Ultrasound imaging sonography uses high-frequency sound waves to view inside the body. Because ultrasound images are captured in real-time, they can also show movement of the body's internal organs as well as blood flowing through the blood vessels. Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging. In an ultrasound exam, a transducer probe is placed directly on the skin or inside a body opening. A thin layer of gel is applied to the skin so that the ultrasound waves are transmitted from the transducer through the gel into the body.
Ultrasound uses high-frequency sound waves to make images of organs and structures inside the body. An ultrasound machine makes images so that organs inside the body can be examined. The machine sends out high-frequency sound waves, which reflect off body structures.

Diagnostic ultrasound can be further sub-divided into anatomical and functional ultrasound. Anatomical ultrasound produces images of internal organs or other structures. Therapeutic ultrasound also uses sound waves above the range of human hearing but does not produce images.
Major Parts of an Ultrasound Machine and Workflow An ultrasound scanner consists of a number of components including a transducer probe, a central processing unit CPU , a monitor, a keyboard with control knobs, disk storage devices, a printer and so on. The most essential component is the transducer probe. This probe both produces the sound waves used in ultrasound and receives their echoes back. It does so by taking advantage of a scientific phenomenon called the piezoelectric effect, also known as the pressure electricity effect. First discovered in by Pierre and Jacques Curie , this effect causes quartz crystals contained in the ultrasound probe to vibrate rapidly and send out sound waves, which are mechanical pressure waves, when an electrical current is applied to them. This same effect also causes the crystals to give off electrical currents when the reflected sound waves from an ultrasound test echo back to them.
