The fluoroscope used has an x-ray source and fluorescent screen. The patient is placed between these two parts of the device. Images are sent via a video camera to a monitor where the surgeon can see them in full view.

Fluoroscopy is a form of x-rays, which involve ionizing radiation. It's this ionizing radiation that has potential risks. Knowing this, the surgeon only uses this device when the benefits of the procedure outweigh the possible negative effects.

Physicians and surgeons who use fluoroscopy always try to use the lowest dose rates possible. Besides exposure to the patient, there is also exposure to the surgeon and staff. And they are exposed for each patient treated.

Improved technology has made it possible to digitize images and reduce the radiation dose even more. For procedures to repair lower leg bone fractures, the average length of time children are exposed to radiation is between 42 and 70 seconds. In some cases, the total time may be as much as two minutes.
