Assessment of Grid Alignment of X-Ray Units in Khartoum State.

Abstract

This study aimed to assess grid alignment for radiology departments in Khartoum state.

A total of 10 x-ray units in radiology departments in Khartoum state from different manufacture were tested by grid alignment test tool and the optical density for radiographic film was read by transition densitometer .

In this study the final result showed that the percentage of grid misalignment for x-ray machines was (40%), less than those with grid alignment x-ray machines (60%).

Which means almost of the grid were found misalignment. The study recommended that all x-ray equipment should be regularly checked using quality assurance tests.
