Evaluation of X-ray Beam Collimation in Adult Chest Radiography.

Background:  Restricting the irradiated volume can reduce X-ray scattering incidents on the image receptor. Proper X-ray collimation during medical imaging reduces a patient's dose while improving image quality. Even though the patient radiation dose due to chest X-ray imaging is low, the 'as low as reasonably achievable' (ALARA) principle should be satisfied, especially for young patients.
