After each soldier is scanned, the information is kept in a database for reference purposes. After scanning bodies for several years, one radiologist discovered a disturbing trend. By examining the data, he found that many American soldiers were dying from bullet wounds to the upper chest. The information was sent to the manufacturers of body armor equipment. Body armor is protective bullet-proof clothing worn underneath a soldier's or police officer's uniform. The radiologist and manufacturer decided to increase the size and length of the body armor for soldiers. Now soldiers are fighting with better equilment.
