轮廓图

Results Compared with conventional ultrasound,sonoCT could suppress the reverberation artifacts in bile duct and gallbladder obviously.Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.Thus,sonoCT raises the reliability of biliary tract tumors diagnosed by ultrasound.

Based on image statistical characteristic, the algorithm can search automatically the boundary start-point using Sobel operator and special template operation, then according to the connection status of every boundary point in its 8-connection neighbor field, seek automatically the search direction, form the whole data collection of a target boundary outline.

该算法依据目标图象特征，在二值图象中利用Sobel算子和特定的模板操作，自适应搜索边界起点；然后，按照每个边界点在其8邻域内的连通情况，自动寻找搜索方向，形成了完整目标边界轮廓数据集。

This method use the silhouette of object in image as feature, after approaching with polylateral, a serious control point can be got, the feature vector of object's contour can be got by calculating the parameter of AR model, which use the sequence of angles got from control points.

该方法以目标二维方面图轮廓为特征，经多边形逼近获得边界控制点，计算出边界控制点对应角序列的AR系数作为相应方面图的特征向量，建立三维目标的在各种姿态下的姿态特征库。

With ILO-92 Otodynamics Analyzer,distortion product otoacoustic emissionsat the 2 f1-f2 frequency were recorded from 86 normally hearing ears in response to four groups of different primary levels (L1=L2=75 dB SPL ; L1=L2=65 dB SPL ; L1=L2=60 dB SPL ; L1=65 dB SPL , L2=50 dB SPL).The average DPOAEs-gram demonstrated a bilobed contour with two peaks at approximately 1.5 kHz and 5 kHz and a "notch" between 2.5 kHz and 3 kHz.Moreover,the contour of DPOAEs-gram had no obvious changes with sex,ear or primary stimulus levels differences.

利用耳动态分析仪ILO-92，对48例听力正常人(86耳)在4组不同原始刺激强度下(L1=L2=75 dB SPL；L1=L2=65 dB SPL；L1=L2=60 dB SPL；L1=65 dB SPL，L2=50 dB SPL)进行畸变产物耳声发射检查，结果发现平均DPOAEs图呈双叶型轮廓：在1.5 kHz和5 kHz附近，2 f1-f2 DPOAEs存在两个高峰，在2.5～3 kHz附近存在一个低谷，此图型结构无性别、耳别差异。

The main target of MRI brain image segmentation is to delineate profiles of neuroanatomical structures and also label each voxel as belonging to a specific structure.

Although much slenderer than the ink lines used for the Vajrapāni, when examined closely, for instance those of the nose and the outline of the face, they prove to be short and discontinuous blunt strokes of the brush, exactly parallel to the more exaggerated strokes of Pl.

此像的墨线比图58的金刚力士像还细，详细观察则发现，如鼻线和脸部轮廓线等不是一笔拉下来的，而是运用了短笔连接的方法，同一笔法，在图55的金刚力士像的描绘上更为夸张。
