Which device is used to restrict the size and shape of an x-ray beam?

The device used to restrict the size and shape of the X-ray beam is the lead collimator. It sits in the beam’s path and uses adjustable shutters to limit the beam to the area of interest, which lowers patient radiation exposure and reduces scatter, while improving image quality. The focal spot is the actual X-ray source on the anode and mainly affects sharpness, not how large the beam is. The anode is the target where electrons hit to produce X-rays. The turbine (rotor) powers the tube. So the lead collimator is the correct choice.
