Ultrasonography is body imaging using ultrasound in medical diagnosis. A skilled ultrasound technician is able to see inside the body using ultrasonography to answer questions that may be asked by the medical practitioner caring for the patient. Usually, a radiologist will oversee the ultrasound test and report on the results, but other types of physicians may use ultrasound as a diagnostic tool. For example, obstetricians use ultrasound to assess the fetus during pregnancy Surgeons and emergency physicians use ultrasound at the bedside to assess abdominal pain or other concerns.
A transducer, or probe, is used to project and receive the sound waves and the return signals. A gel is wiped onto the patient's skin so that the sound waves are not distorted as they cross through the skin. Using their understanding of human anatomy and the machine, the technician can evaluate specific structures and try to answer the question asked by the patient's physician.
