| Moving and holding the C-arm unit during fluoroscopy exposes the surgeon's fingers to high dosages of radiation. |
| The x-ray teams were aware, to some extent, of the danger to themselves from radiation exposure, particularly from fluoroscopy. |
| Ultrasound and X-ray fluoroscopy have long been used in this role, though both have certain drawbacks. |
| The radiologist uses fluoroscopy for a total of 10 to 15 minutes during the entire procedure, and the exposure is intermittent. |
| In fluoroscopy, a moving picture of the body is seen as the test is performed and is recorded on videotape or as still images. |
| However, unlike conventional fluoroscopy, CT fluoroscopy employs a tightly collimated beam that confines the skin dose to a narrow area. |
