What is an ultrasonic probe?
Ultrasonic probe is a type of sensor that uses ultrasound that refers to sounds at frequencies higher than the human ear can detect. Due to the structure of the ear, a healthy young adult can perceive sounds with frequencies of up to about 20 kilohertz (KHZ), although the exact threshold differs from man to man. Ultrasound is useful because it can penetrate through the medium, such as the human body, and provide information about the internal structure of the medium. Ultrasonic probes are used for many different areas such as diagnostic displaying in medicine and quality testing in industry.
When the sound wave passes from one material to another material with another density, part of the sound is reflected back. By measuring the exact times, when the sound waves from the ultrasonic probe echo, the probe can determine the depth of different materials within everything that is scanned. The frequencies used by the ultrasonic probe may vary extremely dependent on its application, between 50 kHz to 50 megahertz.
The best known use of ultrasound is in medicine. The ultrasonic probe can produce images of internal structures such as muscles and soft tissue, as well as the structure of organs. This can be used to diagnose the patient to explore tissues and organs for damage or abnormalities, to detect the condition of arteries and blood flow through and to identify structures such as tumors and kidney stones. Ultrasound is also often used to produce fetal images while it is in the womb. In many situations, ultrasound is preferred to other methods because it is a non -invasive way to see the interior of the body that does not include electromagnetic radiation and therefore does not create the risk of chromosome damage that represents examination methods such as X -rays.
Ultrasonic probe thus May disadvantages. Ultrasound can provide images of the outer surface of the bones, but ultrasonic waves do not penetrate the bone well and are therefore not very effective as a wayHow to examine the interior of the bones or examine the brain with a skull. Ultrasonic waves also do not respond well with gas. As a result, ultrasonic lung imaging is almost impossible, with very limited exceptions and significantly prevents ultrasonic depiction of the pancreas due to the interference caused by the gas in the nearby gastrointestinal tract. Ultrasound also has limited penetration, which can cause problematic ultrasonic imaging when trying to probe deep in the body or when the patient is significantly overweight.
Ultrasound is also used for industrial testing. As with ultrasound in medicine, the ultrasonic probe can be used to ensure the display of the internal structure of the object. This is an extremely valuable ability because it can identify internal abnormalities and defects that would be invisible to Exteriors. It can also detect the microstructural properties of the material, such as grain size, and provide information on the mechanical characteristics of the material.
Industrial ULThe trail is most commonly used for metals and metal alloys, although it can also be applied to other materials such as ceramics. During use, it is commonly used to check the produced objects in terms of manufacturing defects and to check devices that suffer from mechanical voltage, corrosion or other sources. The use of ultrasonic probes for testing is very common in industries related to transport, such as rail and aerospace industry, where fine manufacturing defects or accumulated microstructural damage may have catastrophic consequences unless unnoticed.
