Final answer:
Pelvic sonography, also known as ultrasonography, is the diagnostic procedure used to record sound waves to detect uterine tumors and other pelvic masses.
Step-by-step explanation:
The diagnostic procedure in which a physician records images of sound waves to detect uterine tumors and other pelvic masses is known as pelvic sonography or ultrasonography. This non-invasive imaging technique uses high-frequency sound waves that are transmitted into the body, creating an echo signal that is then converted into a real-time image. Pelvic sonography is particularly useful for examining the uterus, ovaries, and other pelvic structures, and is a crucial tool in diagnosing conditions like endometriosis.
