Methods. We review the previous cases of actinomycosis in the abdomen and pelvis. They were recruited from 1984 through 2001 at Division of Colon and Rectal Surgery, Department of Surgery in the Chang Gung Memorial Hospital.

在本文收集了林口长庚医院大肠直肠外科自1984年至2001年腹部及骨盆腔放线菌感染病例共10例；纪录所有病例的临床症状，子宫内避孕器使用病史，医学影像，血液生化，外科手术术式，术后抗生素使用时程及术后追踪状况。

No mediastinal and hilar adenopathy was found. Conclusion The characteristic appearances of PAP on MSCT correspond to its pathological features.The "crazy paving" sign in geographical areas of pulmonary opacification greatly suggests PAP diagnosis.

本文收集经病理证实的6例PAP，综合国内外有关文献，探讨PAP的影像病理学联系及其多层CT表现特征，旨在提高对本病的认识和诊断。

This dissertation discusses the development of the anus and colon imaging system.

本文主要探讨了肛肠影像检查系统的研制与开发。

The revolution axis of the surface of revolution is calculated by image parameters and top circle of revolution. The rectified image is then used to recover the contour generator and the object is reconstructed.

在理论上讲，利用一张影像就可以实现旋转体的三维重建，但在本文中使用了多张照片，主要是为了获取整个旋转体的纹理。

On the other hand, the difference between the benignancy and the malignancy is successfully identified by DFVI（p=0.004, sensitivity 84%, specificity 64%） because of the protruded microcirculation among thyroid tumor tissue.

本文透过动态影像处理后的DFVI具有良好的检测能力（P=0.004 Sensitivity 84% Specificity 64%），其中主要的关键在於DFVI能够凸显较末端微循环特性。

In this thesis, a binocular stereo vision system is constructed for 3D image reconstruction.

本文的主要目的为发展适用於双目立体视觉系统的三维影像重建理论，并将其应用到微操作系统。

Although classic neuroimaging features of RPLS with involvement of the posterior head regions are easily recognized, features that may generally be regarded as atypical were often present in our patients, such as significant anterior involvement, cortical lesions, recurrent RPLS episodes, foci of permanent injury, hemorrhage into lesions, and unilaterality (Figure 1). High signal intensity on T2-weighted image lesions can occur in regions other than the parieto-occipital areas, frequently involving the frontal lobes, basal ganglia, thalami, or brainstem.

可逆性后部白质脑病综合征典型的神经影像学表现为大脑后部受累，尽管这一点很早就被公认；但可逆性后部白质脑病综合征不典型的神经影像学表现，在本文的患者中则更常见，如：大脑前部明显受累、皮层出现病灶、可逆性后部白质脑病综合征再次发作、脑永久性损伤灶形成、病灶内出血、仅见单侧病灶（图1）；T2像常可于额叶、基底节区、丘脑、脑干等顶-枕叶以外的区域见高信号病灶。

Section 1 discusses the advantages of medical film printer and USB, and put forward one elementary design scheme of the system. The principle of laser printer and the holistic design scheme of system are presented detailedly in Section 2, while Section 3 expounds the technology of USB. Section 4 discusses design scheme of transfer system of the laser printer - includes the development of USB device and CPLD. The test of holistic laser printer and effect picture of medical image are presented in Section5. In the end, a review of this system and some bugs are put forwards at present.

本文主要分为六个部分，第一部分讨论了医用胶片打印机和USB总线技术的特点和发展趋势，并提出了系统的初步设计方案和研究意义；第二部分描述了医用激光胶片打印机的背景、工作原理和系统的各个组成部分；第三部分描述了通用串行总线2.0版(USB2.0)的通信原理；第四部分详细介绍了打印机数据传输系统的设计——包括USB设备的开发和CPLD的硬件和软件设计，并对这个传输系统的性能进行了分析；第五部分介绍了整个打印机的测试结果和实际打印医学影像的效果图；最后对本文做出总结并提出了不足之处和参考价值。

In this paper, the development of CT imaging, CT clinical progress of two major aspects of the past 10 years, further elaborated the medical CT imaging technology development: CT is the emergence of traditional X-ray photography and computer technology combined with the results of imaging Technical people with a new epoch-making stage.

本文从CT成像技术的发展，CT临床应用的进展两个大的方面进一步阐述了近十年来医学影像CT技术的发展现状：CT 的出现是传统X线摄影和计算机技术结合的结果，将影像检查技术带人一个新的划时代的阶段。

Advanced Spaceborne Thermal Emission and Reflection Radiometer level-lA visible image is executed atmospheric correction using two atmospheric radiative transfer model, 6S(Second Simulation of Satellite Signal in the Solar Spectrum) and SBDART (Santa Barbara DISORT Atmospheric Radiative Transfer). The plane-parallel atmospheric model is validated in the high-latitude Antarctica.

本文主要在分析了大气对遥感影像产生的各种影响的基础上，对大气纠正的一般原理和方法进行了回顾和归纳总结，利用两个大气辐射传输模式(6S和SBDART)，对ASTER L1A的可见光波段的影像进行大气纠正，验证了平面—平行大气模型应用于南极高纬度地区的可行性。
