比較在傳統三連片及EOS Imaging System的影像測量長度分析
Comparison of Image Measurement Length Analysis between Traditional Triple Film and EOS Imaging System
摘要
臨床常利用關節測量術（Scanography）來量測病人下肢的長度差異，使用傳統三連片照射時會受照射角度（angle）、放大率（Magnification）、失真（Distortion）、身體厚度等影響，而EOS Imaging System則是水平狹窄射線，較不易受其他因素產生誤差。本研究對象為蒐集2021年6月至8月曾經做過傳統三連片及EOS Imaging System的關節測量術（Scanography）受檢者共35人，年齡介於37到80歲，男性11位、女性24人，量測大腿從股骨頭上緣（Femural Head）到膝關節中心（Knee joints Center）的長度，使用獨立樣本T檢定分析，發現其平均數具有顯著差異，誤差為7.57±1.90，表示在EOS Imaging System量測長度會小於傳統三連片，並由EOS的成像原理推測該攝影方式會更接近受檢者真實的量測長度，可提供臨床在量測三連片長度時可能的誤差數據。
並列摘要
Scanography is often used clinically to measure the length difference of a patient's lower limbs. When using traditional three-slice irradiation, it will be affected by the irradiation angle (angle), magnification (Magnification), distortion (Distortion), body thickness, etc., while EOS Imaging System is a horizontal narrow ray, which is less susceptible to errors caused by other factors. The people of this study are a total of 35 people who have undergone traditional triple-radiography and EOS Imaging System Scanography from June to August 2021, aged from 37 to 80 years old, 11 males and 11 females 24 people, measured the length of the thigh from the upper edge of the femoral head (Femural Head) to the center of the knee joint (Knee joints Center), using independent sample T test analysis, the result was that the p-value was less than 0.001, and the error was 7.57±1.90, expressed in EOS The measurement length of the Imaging System will be smaller than that of the traditional three-slice, and will be closer to the real measurement length of the subject, which can provide clinical error when measuring the length of the three-slice.
