Final answer:
The statement is True.
Step-by-step explanation:
A collimating device is used in x-ray imaging to restrict the size of the x-ray beam and reduce the amount of scatter radiation. This device consists of a collimator, which is made of lead or other dense material, with a small hole in the center. The collimator is placed in front of the x-ray tube, and only a narrow beam of x-rays that passes through the hole can reach the patient.
By collimating the x-ray beam, it helps to focus the radiation on the desired area, improving image quality and reducing unnecessary radiation exposure.
