CLINICAL MEDICINE

Detailed explanation-1: -Collimation: Collimation restricts the x-ray beam to the area of interest using lead shutters within the x-ray tube .

Detailed explanation-2: -The collimator is used to restrict the size and shape of the x-ray beam in order to reduce patient exposure. A collimator may have either a round or rectangular opening. A rectangular collimator restricts the beam to an area slightly larger than a size 2 intraoral film and significantly reduces patient exposure.

Detailed explanation-3: -Collimation, the restriction of the cross-sectional area of the X-ray beam to conform to the size of the image receptor, is usually done with a lead collimator (diaphragm) within the tube head or at the end of a lead-lined cylinder. In addition to controlling the size, collimators also shape the X-ray beam.

Detailed explanation-4: -Collimator. Device used to restrict X-Ray beam size and shape.

Detailed explanation-5: -Collimators have two sets of lead shutters that are used to change the size and shape of the primary beam. Also known as the automatic collimator.
