To fulfill the need of the application of RP technique in medical domain, reverse CAD modeling from medical cross sections is systematically studied in this dissertation. Firstly, Some algorithms related to the research of this dissertation are studied. New algorithms for orientation and inclusion test for simple polygon, an error constrained automatic faring algorithm for B-spline curve and a theorem regarding the termination criterion for subdivision of triangular Bézier patch are proposed. Then based on similarity between contours of adjacent sections, a methodology for surface reconstruction from cross sections is presented. Finally, a virtual measuring method is proposed.

Results 3 cases of lesions were in the gap of"V"shape between iliac muscle and musculus psoas major on the coronal sections in the lower right abdomen closely adjacent to the cecum,which were narrowed. The lesions showed long even T1 and T2 signals similar to mucous wall particularly in T2WI image. The walls of cyst were thin and even. The cysts were round or oval in shape on transections.The cyst were cucurbits in shape in 2 cases and long cannular in a case on coronal sections and arrowy sections and borderlines of the cysts were clear. The terminal of the cysts showed taper in 2 cases. In addition, cecum polypus was found at the placket of the appendix in a case which was not shown on MRI image.

The technical characteristics of the invention is that: the rotor end face tooth profile contains four, five or six sections of tooth curves with the circular nature; when it has five sections, addendum circular arcs and dedendum circles are added to the addendum or the dedendum of the rotor; when it has six sections, both the addendum circular arcs and the dedendum circles are added to the addendum and the dedendum of the rotor at the same time, to form four different combination schemes; there are common tangents at the connection points of the two adjacent teeth forming curves, which has a smooth tooth-profile without cusp, a high-wearing feature, a long life of the rotor, a small leakage triangle, and a good sealing property.

Thirty lavender varieties in five sections were investigated in leaf characters and fragrance. Sections Lavandula and Pterostoechas possessed the highest (7.23) and the lowest (2.01) value of the length/width, respectively. Because sections Lavandula (3.59cm) and Stoechas (3.00cm) possessed the approximate value of the leaf length and leaf width, lavender varieties couldn't be identified only by the leaf character.

在五个不同sections的叶片长宽比调查中，Lavandula与 Pterostoechas 这两个sections分别具有最高（7.23）及最低的数值(2.01)；而Lavandula (3.59)与Stoechas (3.00)两个sections的叶长平均值相近；且在叶宽的调查中，Lavandula (0.49)与Stoechas (0.47)两sections的平均值仍然非常相近，表示仅由叶片外观性状无法精确的判别薰衣草品种。
