3.1 Terminology

3.1.1 Collimator colimator A device that limits the direction of the beam and the size of the beam.

3.1.2 Focus Focus

The center of the beam that is focused by the collimator is called the focus.

3.1.3 "Overlay radiation field" size "overlapingofirradiationfield" size a three-dimensional "superimposed radiation field" composed of a plurality of radiation sources arranged in a certain latitude and longitude, with a dose
