The Society of Diagnostic Medical Sonography (SDMS) defines sonography as diagnostic medical procedure that uses high frequency sound waves (ultrasound) to produce dynamic visual images of organs, tissues, or blood flow inside the body. This type of procedure is often referred to as a sonogram or ultrasound scan.
An Ultrasound technician also known as sonogram technician or diagnostic medical sonographers has the important job of diagnosing medical conditions in patients. They use an ultrasound machine to examine a patientâs inner body to locate any abnormalities, record the findings, and report them to the treating physician.
