Lead Shielding, Collimation Protect Tissues From Radiation

To reduce the radiation dose to the patient undergoing a dental radiographic examination, the imaging protocol must be optimized.  Collimation: One method to decrease radiation exposure during intraoral radiography is by using collimation. For intraoral radiography, the use of rectangular collimation is an excellent way to decrease the radiation dose to the patient. In this approach, a metal collimator is used to reduce the x-ray beam size to the size of the image receptor. Re more...
