sonograms

A sonogram, also known as an ultrasound, is a medical imaging technique that uses high-frequency sound waves to create images of internal body structures. These sound waves are emitted by a transducer, a handheld device that is moved across the skin. The sound waves travel into the body and bounce off different tissues and organs. The transducer then detects these returning echoes, and a computer uses this information to generate a real-time image on a screen.

Sonograms are non-invasive and do not use ionizing radiation, making them a safe imaging option for various medical purposes. They are commonly used during pregnancy to monitor fetal development, assess the health of the mother, and determine the baby's position. Beyond obstetrics, sonograms are utilized to examine organs such as the heart, liver, kidneys, and gallbladder, as well as blood vessels to detect blockages or other abnormalities. They can also be used to guide certain medical procedures, like biopsies, by providing a live view of the area. The images produced are typically black and white, with different shades representing varying densities of tissue.
