Diagnostic Radiology

What is Diagnostic Radiology?

Diagnostic radiology, also known as x-ray, uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. Generally an x-ray procedure follows this process:

  1. The patient will be asked to remove any clothing or jewelry which might interfere with the exposure of the body area to be examined. The patient will be given a gown to wear if clothing must be removed.
  2. The patient is positioned (sitting, standing or laying) by the technologist so the part of the body that is to be x-rayed is placed between the x-ray machine and a cassette containing the x-ray film.
  3. The x-ray beam is then focused on the area to be photographed. Sometimes, multiple x-rays may be needed to view different angles.

Why have an X-ray at St. Luke's?

At UnityPoint Health - St. Luke's we use a Digital Radiography unit to provide the best images available. It allows staff to make changes to the film without having to increase radiation exposure to the patient. All technologists performing x-ray exams are board-certified through the American Registry of Radiologic Technology, ensuring every patient receives the highest standard of quality.
