Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
For example, various kinds of urine test strips have been available for decades, but portable ultrasonography did not reach the stage of being advanced, affordable, and widespread until the 2000s and 2010s. Today, portable ultrasonography is often viewed as a "simple" test, but there was nothing simple about it until the more complex technology ...
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.

An example of Ultrasonic Testing (UT) on blade roots of a V2500 IAE aircraft engine. Step 1: The UT probe is placed on the root of the blades to be inspected with the help of a special borescope tool (video probe). Step 2: Instrument settings are input. Step 3: The probe is scanned over the blade root. In this case, an indication (peak in the ...
A portable ultrasound machine used in the prehospital setting. Emergency ultrasound is used to quickly diagnose a limited set of injuries or pathologic conditions, [4] specifically those where conventional diagnostic methods would either take too long or would introduce greater risk to a person (either by transporting the person away from the most closely monitored setting, or exposing them to ...
The transducer is mounted on the z-axis of the SAM. It can be focused to a specific target layer located in a hard-to-access area by changing the z-position with respect to the sample under testing that is mechanically fixed. [6] The B-scan provides a vertical cross section of the sample with visualization of the depth information.
Ultrasound computer tomographs use ultrasound waves to create images. In the first measurement step, a defined ultrasound wave is generated with typically Piezoelectric ultrasound transducers, transmitted in direction of the measurement object and received with other or the same ultrasound transducers. While traversing and interacting with the ...
