Acoustic Exposure : Amount of acoustic energy a patient receives ALARA Principle : As Low As Reasonably Achievable; Used to reduce the biological effects in humans and the fetus biological effect : effect of ultrasound waves on living organisms, including their composition, function, graowth, origin, development, and distribution. cavitation : interaction of the sound wave with microscopic gas bubbles found in tissues epidemiology 2 : studies of various factors determining the frequency and distribution of disease in the human community ex vivo : refers to experimentation done in or on living tissue in an artificial invironment outside the organism in vitro : refers to the technique of performing a givin wxperiment in a test tube or, generally, in a controlled invironment outside a living organism in vivo : refers to experimentationdon in or on the living tissue of a whole, living organism as opposed to a partial or dead one. Animal testing and clinical trials are forms of in vivo research. Mechanical Index (MI) : describes the likelihood of cavitation occurrin
