X-rays are used for mammography, which is a radiograph of the breast that is used for cancer detection and diagnosis. X-rays combined with computed tomography can help to generate a series of cross-sectional images of the body to view structures from many different angles.

With a fluorescent screen and X-ray, one can obtain real-time images of movement within the body such as beating heart, to view blood flow to the heart muscle. X-rays can also be used to destroy cancerous tumors and cells by damaging their DNA.

Sometimes ultrasound is done from outside the body, while in some cases, it involves placing a device inside your body.
