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.
Ultrasound is used to evaluate fat thickness, rib eye area, and intramuscular fat in living animals. [48] It is also used to evaluate the health and characteristics of unborn calves. Ultrasound technology provides a means for cattle producers to obtain information that can be used to improve the breeding and husbandry of cattle.
Diagnostic medical sonography (DMS), a branch of diagnostic medical imaging, is the use of imaging by medical ultrasound for medical diagnosis. DMS uses non-ionizing ultrasound to produce 2D and 3D images of the body. In Canada, the credentialing for diagnostic medical sonography is the Canadian Association of Registered Ultrasound Professionals.
Used primarily in ultrasound imaging, capturing the image produced by a medical imaging device is required for archiving and telemedicine applications. In most scenarios, a frame grabber is used in order to capture the video signal from the medical device and relay it to a computer for further processing and operations.
Therapeutic ultrasound in medicine ranges from extracorporeal shockwave therapy for the breaking of renal calculi to HIFU in which tumors are ablated. In the research field, use of ultrasound is being explored as a mechanism of enhancing drug delivery, sorting particles, and measuring properties of tissue.
Ultrasound is also limited by its inability to image through air pockets (lungs, bowel loops) or bone. Its use in medical imaging has developed mostly within the last 30 years. The first ultrasound images were static and two-dimensional (2D), but with modern ultrasonography, 3D reconstructions can be observed in real time, effectively becoming ...
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging , using standard ultrasound or Doppler ultrasound . [ 1 ] The visual image formed using this technique is called an echocardiogram , a cardiac echo , or simply an echo .
In medicine, the term is used in the field of [imaging] to describe the practice of medical ultrasonography. [1] According to some scholars, sonology may represent a more advanced application of clinical sonography, chiefly due to the requirement for the use of critical application of both cognitive and radiographic skills in making the ...
