Violation
What is true of a rectangular collimator?
It produces a beam that is collimated to a diameter of 2.75 inches.
It will expose the patient to more radiation than a circular collimator.
It filters out the longer-wavelenght, low-energy x-rays from the x-ray beam.
It restricts the size of the x-ray beam to an area slightly larger than a size 2 intraoral film.
