Abstract

In this study, using an X-ray device (Drgem TS-CSP) and foot phantom (SFT-1556), the angle of the X-ray tube was changed to 30°, 35°, 40°, 45°, and 50°, and the image was evaluated by quantitative and qualitative evaluation. In the blind test, it was the highest at 4.34 points at 40°, and in the part calculation using the Image J program, the angle was the largest at 1750 at 50°. In addition, in the area evaluation excluding overlapping areas, the X-ray tube showed the largest value at 40° Therefore, it was found that the X-ray tube angle was suitable when the X-ray tube angle was 40° as a projection method for observing the calcaneus.

본 연구에서는 X-ray장치(Drgem사 TS-CSP)와 foot phantom(SFT-1556)을 이용하여 발꿈치뼈 후전 축방향 촬영에서 X-ray 튜브의 각도를 30°, 35°, 40°, 45°, 50°로 변화를 주어 각 각도에 해당하는 영상을 흭득한 뒤 정량적 평가와 정성적 평가로 나누어 영상을 평가하였다. 블라인드 테스트에서는 40°에서 4.34점으로 가장 높았으며 Image J 프로그램을 이용한 면적 계산에서는 각도가 50°에서 1750으로 가장 큰 값으로 나타났다. 또한 겹치는 부위를 제외한 면적 평가에서는 X-ray 튜브가 40°일 때 가장 큰 값을 보였다. 그러므로 발꿈치뼈를 관찰하기 위한 촬영법으로는 X-ray tube 각도가 40°일 때가 적합하다는 결과를 얻었다.
