Abstract

The purpose of this study was to evaluate of the usefulness and to develop new auxiliary equipment that can bending angle of the bone of the knee various depending on the thickness of the thigh of the human. The subjects agreed for research purposes and were selected from normal person who do not have past knee-related diseases and grouped thin group A and thick group B for the thigh. We set in order to obtain images in the axial direction of the bones of the knee, $35^{\circ}$ to increase by $5^{\circ}$ angle of knee flexion, $45^{\circ}$, to $55^{\circ}$, and we performed combinations of 9 tests by incident angle X-ray per each angle, $40^{\circ}$, $50^{\circ}$ and $60^{\circ}$. As a result, we have developed an Merchant auxillary equipment of X-ray table integral type in radiographic images which was easy to use and could take images of various integral knee joint angles adjusting different body types. Using the auxiliary equipment, in the case of X-ray incident angle $50^{\circ}$ and $60^{\circ}$ with the knee flexion angle of $40^{\circ}$ in group A, and in group B, Knee flexion angle of $45^{\circ}$ and $35^{\circ}$, the X-ray incident angle at $60^{\circ}$, excellent images were derived. Future, it would be very useful in the examination of patients with a variety of body types.

본 연구에서는 인체의 대퇴부 두께에 따른 다양한 무릎뼈의 굴곡각도가 가능하고 사용이 편리한 새로운 보조기구를 개발하고 유용성을 평가하고자 하였다. 검사 대상자는 연구 목적에 동의하고 과거 무릎 관련 질병이 없는 정상인 중 넙다리 둘레가 얇은 A 그룹과 두꺼운 B 그룹을 선발하였다. 무릎뼈의 축방 영상을 획득하기 위해 무릎굴곡각도를 $5^{\circ}$씩 증가시켜 $35^{\circ}$, $45^{\circ}$, $55^{\circ}$로 설정하였으며, 각 각도별로 X-선 입사각도를 $40^{\circ}$, $50^{\circ}$, $60^{\circ}$로 변화시켜 9 개의 검사 조합으로 검사하였다. 그 결과, 사용이 편리하고 체형변화에 적응할 수 있도록 다양한 무릎관절 각도가 가능한 검사대 일체형 무릎뼈 방사선영상검사 보조장비를 개발하였다. 그리고 이 보조장비를 이용하여 A 그룹에서는 무릎굴곡 각도가 $45^{\circ}$에서 X-선 입사 각도가 $60^{\circ}$$50^{\circ}$ 그리고 B 그룹에서는 X-선 입사 각도가 $60^{\circ}$에서 무릎굴곡 각도가 $35^{\circ}$$45^{\circ}$에서 우수한 영상이 도출되었다. 향후 다양한 체형의 환자들의 검사에 매우 유용할 것으로 사료된다.
