Most of previous segmentation approachs make use of the surface curvatures or the approximative polynomial coefficients which are very sensitive to noise, but the mathematical morphological operations are robust, so another main advantage of our scheme is its good noise immunity.

以前的大多数分割方法都使用表面的曲率或近似多项式的系数，表面的曲率或近似多项式的系数的计算对噪声很敏感，而数学形态学运算具有较好的抗噪声性，因此我们的方法的另外一个优点是它具有良好的抗噪声性能。

Objective: To establish the optimal height of the strut-graft for clinical surgery, this study analyzed the effect of change in strut-graft height on the lordotic curvatures and immediate biomechanical stability of the cervical spine on which corpectomy and strut-graft reconstruction with different height was performed.

目的：研究中下颈椎前路单椎体次全切除减压后不同撑开高度支撑植骨对颈椎曲度和颈椎即刻运动稳定性的影响，为临床手术确定合适的植骨高度提供参考。

Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

There were six themes in this study. First of all, the geometry of in-vivo human pinna and ear canal was measured non-invasively. The 3D model of pinna and ear canal was reconstructed and then measured based on the image processed by HRCT. Second, the 2D curvature of in-vivo human ear canal was measured non-invasively. The angles and curvatures of superior and inferior walls of first and second bends were measured. The 2D curvature of ear canal was computed by sine and cosine laws. Third, the in-vivo human ear canal was reconstructed by RE. The distribution of sound field was analyzed by FEM. The data obtained in this study can be the reference for clinicians and audiologists. Fourth, the 3D model of earmold of hearing aids, including the ear shell and the housing, was reconstructed by RE based on the image of in-vivo human ear canal obtained by CT.

本研究主题其四，对於听力受损之患者往往皆须选配助听器帮助其放大声音，其中耳模是助听器的外壳，也是接触到耳朵的仪器，而耳道型助听器系位於耳甲艇及耳甲腔延伸至耳道第一弯道处，在制作耳模必须利用灌模方式来取得紧配之耳模，其中耳模在助听器的使用过程中，常因耳模松脱，无法与人耳道紧密配合而造成漏音，因此，利用活体人外耳道电脑断层影像，重建耳道型助听器耳模之三维立体模型影像，其中耳模包括了耳壳及耳模内部空间，并进行几何外型量测，探讨耳道型助听器之体容积大小，也提供了制作耳模时快速、精确度高、减少翻模及修模次数，可减少误差率之方法。

In addition, we can configure different target curvatures to get versatile parameterization results.

通过对目标曲率不同的合理设置，我们还可以获得不同的参数化效果。
