Focus assessed transthoracic echocardiography (or FATE) is a type of transthoracic echocardiogram, or sonogram of the heart, often performed by non-cardiologist.The protocol has been used since 1989 and has four projections; subcostal four-chamber, apical four-chamber, parasternal long axis and parasternal short axis.
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
The American Registry for Diagnostic Medical Sonography (ARDMS), incorporated in June 1975, is an independent nonprofit organization that administers examinations and awards credentials in the areas of diagnostic medical sonography, diagnostic cardiac sonography, vascular technology, physicians’ vascular interpretation, musculoskeletal sonography and midwifery ultrasound.

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.
Stratosphere sign is a clinical medical ultrasound finding usually in an eFAST examination that can prove presence of a pneumothorax. The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the fourth and fifth intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode ...
[10] Oncology. Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time ...
[2] [3] [4] As an ultrasound-based method with low sound pressures, USCT is a harmless and risk-free imaging method, suitable for periodical screening. As USCT setups are fixed or motor moved without direct contact with the breast the reproduction of images is easier as with common, manually guided methods (e.g. Breast ultrasound ) which rely ...
