已经开发出一种用于确定横截面积的新复制成型技术。已经研究了该技术的准确性。对面积测微计和激光测微计进行了比较，以确定每种技术的相对精度。复制技术系统地将横截面积低估了 6.2%。然而，当校正这种收缩伪影时，残余误差为+/-1.8%。相对于修正的复制方法，计算得出面积千分尺低估了横截面积 16.2+/-6.9% (SD)，并且假设凸形横截面会导致激光测微计高估肌腱的横截面积平均 2.3+/-1.5% (SD)，对于“圆形”韧带样本高估 4.7+/-2.5%，以及 横截面有明显凹陷的十字韧带束为19.1+/-6.4%。该成型方法被认为对于具有不规则横截面的软组织标本特别有用。版权所有 (C) 1996 爱思唯尔科学有限公司
A new replica moulding technique for determining cross-sectional area has been developed. The accuracy of this technique has been investigated. Comparisons have been made with the area micrometer and the laser micrometer to establish the relative accuracy of each technique. The replica technique systematically underestimated the cross-sectional area by 6.2%. However, when this shrinkage artefact was corrected for, the residual error was +/-1.8%. Relative to the corrected replica method, it was calculated that the area micrometer underestimated cross-sectional area by 16.2+/-6.9% (SD) and that the assumption of a convex cross-section would have caused the laser micrometer to overestimate cross-sectional area by an average of 2.3+/-1.5% (SD) for tendon, 4.7+/-2.5% for 'round' ligament specimens and 19.1+/-6.4% for cruciate ligament bundles with obvious concavities in their cross-sections. The moulding method was thought to be particularly useful for soft tissue specimens with irregular cross-sections. Copyright (C) 1996 Elsevier Science Ltd.
