Abstract
Radiological examination of the head bone is an integral part in the management of patients suffering from head trauma. This is because X-ray of the head bone is still quite significant in diagnosing fractures of the head bone. X-ray examination of cases of injury to the facial bones required two times the examination of the lateral head of high and low intensity x-ray to produce different image information due to heterogeneity of the head bone. At this time there is no method to improve image quality by combining the two images. in this study a method of improving image quality with fusion on high-low lateral head bone radiographs is proposed. This research is an experimental study to compare two variables measured from unequal (free) samples, where the group that is compared is more than two, namely the quality of lateral images of high intensity head, low intensity and fusion. Image quality assessment is done using a histogram which is then analysed using the Friedman test. The results showed that the average gray level on the highest histogram was sequentially at high intensity, fusion and finally at low intensity. The statistical test results obtained p value 0.007 which means that there are differences in the quality of lateral head images at high intensities, low intensities and fusion. Fusion image quality obtained grey level values that are between high and low intensity images, this illustrates that using of image fusion is able to provide more complete image information. © Published under licence by IOP Publishing Ltd.
