연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Mortise view 검사는 발목관절 검사로써 발목관절의 외상이나 염좌, 탈구가 의심되는 병변의 유무를 관찰한다. mortise view 검사 시 사용되는 보조기구는 영상에 인공물을 발생하거나, 종류가 다양하지 않아 환자 맞춤형으로 제작되지 않고 가격이 비싸다. 이에 본 연구는 3D 프린팅 기술을 이용하여 mortise view 검사보조기구(ShinHan Device; SHD)를 제작하였다. SHD를 사용했을 때와 시제품인 hologic tool을 사용했을 때의 목말종아리관절, mortise 관절, 목말정강관절의 길이를 5명의 연구자가 측정하여 평가하였다. SHD를 사용했을 때 평균값의 범위는 TTJ에서 39.42~39.47 mm, TCJ 31.41~31.57 mm, MJ 21.21~21.23 mm의 범위로 나타났다. hologic tool를 사용했을 때는 TTJ 39.73~39.79 mm, TCJ 31.46~31.50 mm, MJ 21.31~21.35 mm의 범위로 측정되었다. 본 연구결과, 모든 위치에서의 오차범위가 hologic tool에 비해 SHD를 사용 때 TTJ는 24%, TCJ는 17%, MJ는 36% 감소하였으며, SHD를 사용하였을 때 재현성 높은 검사자세를 구현할 수 있었으며(ICC=0.99), hologic tool에서 발생하던 인공물을 제거한 영상을 획득할 수 있었다.

The mortise view radiography procedure is an ankle joint examination and observes the presence of trauma, sprain, or dislocation suspected in the ankle joint. The auxiliary equipment used during the mortise view radiography procedure can generate artifacts in the radiograph images and is not diverse...

제안 방법

  • In this study, we evaluated the clinical utility of a 3D-printed ankle joint examination assistive device to achieve a consistent ankle joint rotation ankle and examiner posture, as well as standardized image depiction during the mortise view examination.
  • Statistical analysis was performed using the SPSS software (SPSS version 26, IL, United States). The data evaluation approach of this study involved five assessors presenting descriptive statistics (mean, standard deviation, minimum, maximum values) for the measurements taken at each location from the 3,000 images acquired using the SHD and Hologic tool methods. Furthermore, the interrater reliability (intraclass correction; ICC) among the operators for the measurements was analyzed.
  • The study compared the changes in the lengths of TTJ, TCJ, and MJ when using SHD and Hologic tools based on the measuring operators. The results of the study showed that the ICC values for TTJ, TCJ, and MJ were all 0.
  • This suggests that SHD was easier to use for the mortise view examination positioning, leading to these results. Therefore, this study utilized 3D printing technology to create assistive devices that can be customized for patients, making it easier to maintain their posture during examinations. However, one limitation of this study was that the angles were designed specifically for the mortise view examination.

대상 데이터

  • In this study, image measurements were conducted by five operators from the Radiology Department at Shinhan University who participated in the study. They performed 10 measurements each at different times over a span of 10 days.
  • In this study, the radiographic imaging equipment (Innovision DXII, DK medical system, Republic of Korea), and the foot phantom used was the RSD Anthropomorphic food ankle phantom RS-116T (Universal medical, CA, United States). Two types of auxiliary assistive devices were used: a self-made assistive device using a 3D printer by the researchers (ShinHan Device; SHD) (Fig 1-(b)) and the existing prototype called hip positioning fixture for Hologic bone densitometer hip positioning fixture 010-0141 (Hologic, MA, United States) (Fig.
