Ultrasound has many similar applications and uses that we come across in our daily lives. Ultrasound is sound with frequency above the human hearing range - we say that it is too high-pitched for humans to hear. Definition ; Doppler: Doppler ultrasonography is a medical non-invasive study of the heart and blood vessels, using ultrasound with high-frequency waves. Ultrasound imaging uses sound waves to produce pictures of the inside of the body. How to use ultrasonography in a sentence. This type of Doppler uses a computer to change sound waves into different colors. Interventional ultrasound, i.e., US-guided interventions, are diagnostic or therapeutic minimally invasive procedures guided by real-time ultrasound imaging, preferably using attachable needle steering devices. The test has been around for decades, and the US Food and Drug Administration (FDA) considers it reasonably safe for use in most individuals, including pregnant women.. Also called. CONTINUE .

Often utilised for its excellent axial and temporal resolution of structures, M-mode (or motion mode) is a form of ultrasonography in which a single scan line is emitted, received, and displayed graphically. Ultrasound ( US) is an imaging technology that uses high-frequency sound waves to characterize tissue. Ultrasound definition. The human ear does not perceive this sound and it is commonly audible to bats. Ultrasound (sonography, Doppler study) is a non-invasive diagnostic medical procedure that examines internal organs and various parts of the body. Ultrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range). 2. Diagnostic sonography (ultrasonography) is an ultrasound-based diagnostic imaging technique used for visualizing subcutaneous body structures including tendons, muscles, joints, vessels and internal organs for possible pathology or lesions.
