"First we calculated distances from the external contour to the distal end of the tumor using the CT images of the patient," he said."The depth values were then mapped to a coronal projection of the PTV. Then we binned the depth values to the target energies."

他指出，首先我们透过病患的CT影像计算自外在轮廓到远端肿瘤边缘的距离，接著将深度数值与「计画目标体积」PTV的冠状投射范围对照，然后将深度数值放进目标能量。

Searching for the object's concavities of active contour model is a dynamic optimization problem.

主动轮廓线模型凹陷边界点的寻优属于动态优化问题，由于其复杂性，传统方法不能准确搜索到最佳边界点。

The new method overcomes the disadvantages of the sensitivity of active contour models to its initial position, the poor convergence to boundary concavities which existed in the traditional Snake algorithm, sensitivity to noise and complex computation.

从而克服了参数主动轮廓线模型对初始曲线敏感、噪声敏感和不能收敛到凹陷的边缘问题和几何主动轮廓线模型水平集方法计算量大等问题。

After repeated studies, we found that gradient vector flow deformable model is robust to model initialization and not stagnant by local energy minimum, but still is difficult to handle boundary concavities. Thus, we develop a modified technique to overcome this drawback. This technique makes active contour further progress into concavities.

经过反覆实作，我们发现GVF较不受模型初始值之影响，而且不会因局部极小能量而停滞，然而此法仍难以进入凹陷处，因此我们也研发了一种改良技术来克服这个缺点。

Firstly, the thesis discusses the edge extraction and vectoring methods in order to get the contour profile of the cross-section, based on the digitalizing techniques of layer measuring.

为此，提出了轮廓特征点计算方法和基于特征点的断面轮廓图形形状分析方法，同时通过建立过渡环和附加面域的方法来处理相邻的突变截面。

Use of secondary flow in the base also elongates the separation bubble, thereby forming an "aero-dynamic" contour that resembles the truncated portion of the spike.

使用二次流在该基地也elongates分离的泡沫，从而形成了&航空动态&轮廓类似于截断部分的穗。

A kind of special encasing material is developed and used to reinforce the part in the project, which can compound different color according to different requirement .It provides obvious gray scale contrast between the image of part and encasing material and it can obtain the accurate contour of a parts cross section. This kind of material has good machinability, additives and proper toughness. The whole encasing process is simple and rapid.

本项目开发研制了一种专用封装材料来封装被测零件，封装材料根据不同的需要，可以配置出不同的颜色，使得与被测零件的图象颜色具有较明显差别，能够提取出精确的零件截面的边界轮廓，并且具有良好的粘合性能、机械性能和适当的韧性，操作也比较简单。
