Reduction Of Backscattered Radiation For X-Ray Image Quality Enhancement.
PhD thesis, Perpustakaan Hamzah Sendut.
Abstract
This study mainly aims to reduce backscattered radiation inside an X-ray
room. The characteristics of X-ray attenuation in several materials such as lead,
copper, iron steel, aluminium, and concrete have been investigated under different
exposure parameters to measure their abilities to attenuate incident X-ray and to
reduce backscattered X-ray. Lead and Iron presented good attenuation values for
incident X-ray at radiographic diagnosis energy range (50 -110 kVp), whereas iron
and aluminium reflected the least amount of backscattered radiation dose. A number
of anti-scatter grids have been designed and fabricated from iron steel and
aluminium, because of their relatively better abilities to reduce backscattered
radiation compared to other materials.
