Some ways of providing education for non-radiologist physicians who perform fluoroscopic procedures can include:
1. creating increased awareness of radiation dose for specific procedures through discussion.
2. establishing goals for lowering radiation dose for patients, assisting personnel, and themselves.
3. radiographers helping physicians performing fluoroscopic procedures by informing them that they have reached a specific dose, thereby giving fluoroscopists the opportunity to decide to continue or stop a procedure.
