Ultrasound involves the use of high-frequency sound waves to create images of organs and systems within the body.
|
|
Ultrasonography is a diagnostic technique that involves directing high frequency sound waves at tissues in the body to generate images of anatomical structures. Ultrasonography is also called sonography, diagnostic sonography, and echocardiography...

X rays are a type of radiation used in imaging andtherapy that uses short wavelength energy beams capable of penetrating most substances except heavy metals.
|
|
X rays are electromagnetic radiation that differentially penetrates structures within the body and creates images of these structures on photographic film or a fluorescent screen. These images are called diagnostic x rays.
