Chest X-ray

Chest X-ray

A chest X-ray is a radiographic test that uses a small amount of ionizing radiation to produce images of the chest cavity. The test is performed by a radiologic technologist, who positions the patient in front of an X-ray machine and directs a small dose of radiation through the chest. The radiation is absorbed by the tissues in the chest, and the image is captured on film or digitally.

Why is a Chest X-ray done?
