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.
Ultrasonic cavitation device is a surgical device using low frequency ultrasound energy to dissect or fragment tissues with low fiber content. It is basically an ultrasound probe (acoustic vibrator) combined with an aspirator device ().
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 ...
Relatively high-energy ultrasound can break up stony deposits, ablate tissue, accelerate the effect of drugs in a targeted area, assist in the measurement of the elastic properties of tissue, and sort cells or small particles for research.

Subdermal hematoma (under the skin) Intramuscular hematoma (inside muscle tissue) Skull/brain: Subgaleal hematoma – between the galea aponeurosis and ...
This is a shortened version of the seventeenth chapter of the ICD-9: Diseases of the Digestive System.It covers ICD codes 800 to 999.The full chapter can be found on pages 473 to 546 of Volume 1, which contains all (sub)categories of the ICD-9.
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.
As an ultrasound acoustic wave cannot propagates through the compressive tissue, such as rubber, human tissues part of it and the ultrasound energy will be turned to converted as heat, with focused beams, a very small region of heating can be achieved the part of shallow deep in tissues (usually on the order of 2~3 millimeters).
