Diagnostic Medical Sonography Degree Prerequisites: When enrolled in a degree seeking program, most colleges or universities will have a core curriculum that is required before starting ultrasound courses. The core studies are designed to prepare students for the specialized and more technical nature of the degree major.
Prior to 1970, many individuals performed sonography for research purposes and those assisting with the imaging were considered technicians or technologists, and in 1973 in the United States the occupation of diagnostic medical technology was established as sonography become more widely used within healthcare settings.

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.
Technicians who use ultrasound to examine the heart chambers, valves, and vessels are referred to as cardiac sonographers. [1] They use ultrasound instrumentation to create images called echocardiograms. An echocardiogram may be performed while the patient is either resting or physically active. Technicians may administer medication to ...
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 reflected ultrasound is received by the probe, transformed into an electric impulse as voltage, and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency, the lesser the depth reached. [9]
Texas Tech's biggest leap came in the online bachelor's programs, where the university vaulted to No. 50, up 79 spots from 2023 and 110 spots from 2022, and in online master's education programs ...
