残肢形状捕捉（铸型）的一致性对接受腔匹配的质量有很大的影响。磁共振成像被用来建立一个可靠的参考网格，两种常见的铸造方法，手离和Hands-on-intercast和intracast的形状和体积的一致性。残肢铸造12人与单侧膝下截肢，扫描两次，每个铸造概念。随后，每个截肢者的所有四个体积图像被半自动分割并使用胫骨配准到一个共同的坐标系，然后计算形状和体积差异。结果表明，两种铸造方法具有铸造体积的一致性，两种方法之间的体积差异不显著。根据一只袜子的体积标准，管间和管内平均体积差异无临床意义。由于形状差异的变异系数很高，所以无论是放手法还是动手法都不会产生一致的残肢形状。在不干预铸造中，残肢的最终形状是可变的，但差异无临床意义。对于动手铸造，形状差异等于插座配合不良的最大可接受限值。
Residual limb shape capturing (Casting) consistency has a great influence on the quality of socket fit. Magnetic Resonance Imaging was used to establish a reliable reference grid for intercast and intracast shape and volume consistency of two common casting methods, Hands-off and Hands-on. Residual limbs were cast for twelve people with a unilateral below knee amputation and scanned twice for each casting concept. Subsequently, all four volume images of each amputee were semiautomatically segmented and registered to a common coordinate system using the tibia and then the shape and volume differences were calculated. The results show that both casting methods have intra cast volume consistency and there is no significant volume difference between the two methods. Inter- and intracast mean volume differences were not clinically significant based on the volume of one sock criteria. Neither the Hands-off nor the Hands-on method resulted in a consistent residual limb shape as the coefficient of variation of shape differences was high. The resultant shape of the residual limb in the Hands-off casting was variable but the differences were not clinically significant. For the Hands-on casting, shape differences were equal to the maximum acceptable limit for a poor socket fit.
