Answer:
sonography
Explanation:
"Sonographers, meanwhile, are trained in using sound waves to take images of tissues and organs in the body. These technologists, using specialized equipment, send high-frequency sound waves through the patient’s body. Consequently, echoes bounce off the tissues and organs and a special computer converts the echoes into visual images. For more information on careers in radiologic technology, visit the American Society of Radiologic Technologists’ website. This is a professional organization for people employed in radiation therapy and medical imaging."
