Development and Application of Reconstruction System for Morphological Study by Using Workstation

我们一直在为形态研究人员开发一个三维重建系统。在开发过程中，我们阐明了各种问题，我们正在逐步解决这些问题。计算机重建是一个耗时的过程，包括数字数据的传输、处理和管理。这给了我们辛勤的劳动。为了改进它们，我们开发了一个集成系统。利用工作站的优势，机器通过局域网相互连接，局域网进一步延伸到互联网(由日本文部省信息中心运营的SINET)。这使我们能够与世界各地的许多研究人员合作。在互联网计算与形态研究人员重构系统的整合过程中，我们注意到了形而上学的问题。为了寻求解决方案，我们公布了我们的经验、想法和技巧。由于彩色图像数据量巨大，我们将其以模拟数据的形式存储到激光录像机(LVR)中，通过工作站控制进行检索，并将其作为数据库，通过模数转换获得工作站上的数字数据。通过工作站对显微镜工作台和LVR的控制，将广域的组织切片全彩图像自动分割成多个片段，存储到LVR中，并以蒙太奇图像的形式在工作站显示器上重新显示。显示器上感兴趣的结构的轮廓是通过样条函数将代表点相互连接来获得的，并且通过指定轮廓的内部部分来产生三维匹配数据。使用RPC(远程过程调用)将耗时的进程分布到高性能的CPU服务器上。

We have been developing a three-dimensional reconstruction system for morphological researchers. In the development process, we elucidated various issues, which we are resolving step by step. The computer reconstruction is a time consuming process including the transportation, handing and management of digital data. This gives us laborious works. To improve them, we have developed an integrated system. Taking advantages of workstations, machines are connected with each other via a local area network, which is further extended to the Internet (SINET run by the Information Center of the Ministry of Education, Science and Culture in Japan). THis enabled us to cooperate with many researchers in wide area on the world. In the process of the integration of the Internet computing and the reconstruction system for the morphological researchers, we noticed metaphysical issues. In search of the resolution, we published our experiences, idea and tips. Due to the immense color image data, we stored them as analog data into a laser video recoder (LVR), retrieved them with the help of workstation control, and made them as a database to get digital data on workstations via analog/digital conversion. By controlling the stage of microscope and the LVR with the workstation, the wide area full color image of histological section are automatically splited into many pieces, which are stored into the LVR,miniaturized and redisplayd as a montage image on the workstation display. The outlines of structures of interest on the display are obtained by interconnecting representative points via spline function, and three-dimensional mataball data are produced by designating the inner portion of the outline. The time-consuming processes are distributed to high performance CPU servers by using RPC (Remote Procedure call).
