The science of sonography might be summarised as "using sound to see." Diagnostic medical sonographers utilise specialised equipment to direct safe, high-frequency sound waves to specific parts of the body. The waves' echoes are gathered and converted into animated visuals. 

The sonographer is educated to choose certain images and record them for use by a clinician in making a diagnosis or monitoring a medical condition, such as pregnancy. Obstetrics and gynecologic sonography, abdominal sonography, neurosonography, ophthalmologic sonography, vascular technology, or echocardiography are some of the specialties available. 

Many two- and four-year institutions offer training for his profession. The American Registry of Diagnostic Medical Sonographers offers certification tests. Registration requires an associate's degree or above. While diagnostic medical sonographers work in a highly technical field, they must also be good with people. They should be able to calm a nervous patient and explain the procedure in a soothing manner. 

They may be responsible for preserving patient records, changing and maintaining equipment, and creating work schedules. This profession, sometimes known as ultra-sonography, provides an important and painless healthcare service.
