Results (1) The operation time:the mean time was (40.3±6.1) minutes.(2) pathological examinations: a few necroses in endometrium (2/15 cases) and shallow myometrium (12/15 cases).(3) According to the skin radiation measurements of 20 cases, the highest dose was found in sacrum projection（32.88cGy）,came ovary(16.64cGy) and adrenal gland(16.64cGy) in the second and third. All the radiation doses was within the safe range in normal condition.(4) The collateral circulation from ovarian artery to uterus was confirmed by angiography and 3-D color Doppler imaging.

结果 （1）手术时间：平均（40.3±6.1）min；（2）病理检查：部分病例子宫内膜（2/15）、子宫浅肌层（12/15）出现少量的坏死，余未见异常；（3）患者术中所受X线辐射剂量：骶尾部皮肤处32.88cGy、卵巢16.64cGy 、肾上腺腰部皮肤投影处12.44cGy，均在正常安全剂量范围内；（4）侧支循环：经卵巢DSA造影及三维彩超证实术后卵巢动脉向子宫体提供少量的血流。

In order to obtain the correct height reconstruction of a measured object through the traditional Fourier transform profilometry, the connecting-line between the exit pupil of the projecting lens and the entrance pupil of the imaging lens must be horizontal and set to parallel to the reference plane.

在拍摄过程中，采集完参考平面的光场后，只需要再采集一帧条纹图形，通过傅里叶变换、频谱滤波、逆傅里叶变换、相位展开等处理后就能得到物体的三维数据。采用传统的傅里叶变换轮廓术进行三维物体面型测量时，必需保证投影装置出射光瞳和成像装置入射光瞳的连线与参考面平行，并且它们的光轴应在同一平面上，才能得到较为准确的测量结果。

Theoretical analysis and experimental results suggest that its coding accuracy based on a N-sized codebook is comparable with that of the conventional vector quantization with a N〓-sized codebook, and much better than multi-stage VQ based on two N-sized codebooks, whereas its computational complexity is much lower than the latter ones.

理论分析和实验结果表明：码书大小为N的线上投影法的编码精度与码书大小为N〓的矢量量化法相当，并且明显优于用两个大小为N的码书构成的两级矢量量化法，而其码书生成和编码的计算复杂度远低于后者。
