Radiography is a branch of medicine that focuses on using radiation or other techniques to create relevant medical images. In this field, you may use imaging equipment that utilizes x-ray, ultrasound, or MRI techniques based on what information doctors think is necessary to make an accurate diagnosis. Radiography is usually used to investigate bones and organs, but several radiography positions exist outside of the medical field. For example, industrial radiography is used to verify the internal structure of assembled products like cars and machines. This can help a company determine whether or not the product is ready to ship. Many radiography machines are safe under normal circumstances but can be dangerous if misconfigured, so technicians must ensure the safe operation of imaging equipment and calling for help if there's a problem with the machine.
