Final answer:
Ultrasound imaging uses sound waves and high-frequency energy to create images of the body's internal structures, making it a crucial, non-invasive diagnostic tool in medicine.
Step-by-step explanation:
Ultrasound uses sound waves and high-frequency energy which are transmitted through matter to create images. This imaging technique, known as ultrasonography, involves emitting ultrasonic waves from a transducer that reflect off of different structures within the body. A computer then converts the echo signals into real-time images of the body's anatomy and physiology, making it an invaluable tool in medical diagnostics.
These sound waves are partially absorbed by tissue, with the reflected waves used to construct an image. The technology is non-invasive and is especially favored in delicate scenarios like pregnancy because it avoids the use of harmful radiation. Doctors use ultrasonography to examine internal organs, assess fetal development, and even perform medical therapy, where high-intensity ultrasound can treat conditions like gallstones or cancerous tissue.
