Abstract
Introduction: X-ray is produced in form of divergent beam. The beamdivergence results to blurring effect that influences image diagnosis. Thus, the blurring effect assessment should be enrolled within the quality control (QC) program of an imaging unit.Method: this study is conducted by using multiparameter double holescontrast-detail (MDHCD) phantom to define the blurring effect and its associated factors which include the source-to-image receptor distance (SID), object thickness, and object distance from centre. This study was conducted by exposing the phantom with x-ray where the factors were manipulated. ImageJ software was used to analysethe phantom images by plotting pixel intensity curves and measuring area under the curves (AUC) of two areas (area1 and area2). 2). Results: From the result, increased SID (750-1250-1750) mm, decreases the AUC reading (area 1; 415-328-306, area 2; 454-339-308) Pixel-per-millimeter (Ppmm). When object thickness increases (13-18-23) mm, AUC increases (area 1; 262-321-349, area 2; 274-333-386) Ppmm. Lastly, when the distance from center is increased (50-100-150) mm, AUC increases (area 1; 401-438-449, area 2; 459- 477-487) Ppmm. Conclusion: In conclusion, the blurring effect is more prominent as the SID decreases and the object thickness and distance from center increase.
