To evaluate bone density in the middle of the skeleton, a sizable scanning arm will be passed over your body during the scan. A small beam of low-dose X-rays will be passed across the area of your body being scanned as the scanning arm is progressively moved over your body. The Video shows more in detail on how the Dexa Scan works.
