The ultrasound equipment must be sufficiently high-quality to give a correct image-processing result, which can then provide invaluable information, mainly at the superficial level. It must be able to provide both color and Doppler imaging, technologies that developed alongside the development of ultrasound. Doppler measurements which trace the ...
Copula is a Latin term meaning link or tie. It can also refer to: Math. Copula (probability theory), a function linking marginal variables into a multivariate ...
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.
Copula has also been used to predict the histological diagnosis of colorectal lesions from colonoscopy images, [57] and to classify cancer subtypes. [58] A copula-based analysis model has been developed in the field of heart and cardiovascular disease, for example, to predict heart rate (HR) variation. Heart rate (HR) is one of the most ...
The word copula derives from the Latin noun for a "link" or "tie" that connects two different things. [1] [2] A copula is often a verb or a verb-like word, though this is not universally the case. [3] A verb that is a copula is sometimes called a copulative or copular verb. In English primary education grammar courses, a copula is often called ...
Ultrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults ...
By changing the pulse delays, the computer can scan the beam of ultrasound in a raster pattern across the tissue. Echoes reflected by different density tissue, received by the transducers, build up an image of the underlying structures. Weld examination by phased array. TOP: The phased array probe emits a series of beams to flood the weld with ...
