DETECTING CANCER THROUGH SOUND
Ultrasound, also called ultrasound scanning or sonography, is an imaging method that uses sound waves to create an image of a part of the body. A computer program is used to analyze the echoes of sound waves sent into the body and generates an image on screen.
Unlike mammograms, which use radiation (x-rays), ultrasounds expose the body region of interest to high-frequency sound waves. Ultrasound images are captured in real time; that is, not only do they show the structure of a particular part of the body, but they can also show movement of the body’s internal organs as well as blood flowing through vessels
