Proper collimation in computed tomography (CT) is essential for optimizing image quality and minimizing radiation exposure. An effective collimation systems ensures thate X- ray beom im precisely shaped andd directed, reducing scatter and improwing g contrastt resolution. This article consixes key consignations in designing collimation systems for CT scanners.
