Comparison of X-ray Beam Overlap Measurements between Digital X-ray Ruler and Collimator Test Tool
Comparison of X-ray Beam Overlap Measurements
Keywords:
Digital X-ray ruler, Collimator test tool, X-ray beam overlap measurementsAbstract
A newly developed tool, the Digital X-ray ruler, has been designed for evaluating X-ray beam and beam overlap. The objective of this study was to compare X-ray beam overlap measurements between the Digital X-ray ruler and the collimator test tool, which was the current standard device used for measuring beam overlap in general radiography X-ray machine. The test results comparing X-ray beam overlap with the light field revealed that in clear-beam general diagnostic X-ray machines, the digital X-ray ruler had a maximum difference from the collimator test tool at 0.03 centimeters, accounting for 0.34%. Meanwhile, in general diagnostic X-ray machines with unclear beams, the maximum difference between the beam overlap and the light field was 0.09 centimeters, calculated as 1.41%. Therefore, it could be summarized that there was no significant difference in measurement results between the two instruments. The Digital X-ray ruler can be used as a suitable alternative to the collimator test tool.
