Ultrasound is a medical imaging technique that uses inaudible, high-frequency sound waves and their associated echoes to produce images of the body’s tissues and internal organs.
During the exam a radiologist or an ultrasonographer (a technologist who specializes in ultrasound exams) places a jellylike substance on the skin of the area in question. A probe that is attached to the machine is manually placed over the area and the machine then transmits a high-frequency sound wave into the body. Images are relayed in real time, therefore movement of the patient’s organs (or developing baby in the case of a pregnant woman) can be captured by the person doing the exam. The images are then relayed to a radiologist to interpret the exam results.
