Ultrasound targets are often used to examine the uterus, which is a five-letter word, 'uteri'. Ultrasound is a non-invasive imaging technique that uses sound waves to create images of organs and structures inside the body. It is commonly used to diagnose and monitor pregnancies, as well as to detect tumors, cysts, and other abnormalities. Ultrasound targets can also be used to measure the size and shape of organs, as well as to assess blood flow.
