Ultrasound imaging, a common diagnostic tool in gynecology, operates on the principles of sound waves and their interaction with body tissues. High-frequency sound waves are emitted by a transducer, which then receives the echoes bounced back from different tissues. The time delay and strength of these echoes are processed to create visual images of the internal structures, such as the uterus, ovaries, and developing fetus. This technique is essential for monitoring pregnancy and diagnosing gynecological conditions like ovarian cysts and uterine fibroids.
