数字化虚拟人体的科学意义及应用前景

人体信息的数字化是将医学是信息技术，计算机技术、虚拟现实技术相结合的科技前沿性研究课题。许多国家已建立或正在建立虚拟人体模型。这种模型以人体断面连续切片为建模基础，对信息技术发展起来的计算医学加以数字化，定量地模拟人体的生理病理状况，在医学及其他多种学科领域均具有广泛的应用前景。本文介绍了：（1）国际上切片建模概况。1994年美国完成的可视人计划数据集，包含男女各1组数据，已为国际上广泛应用开发，韩国于2000年完成了1例韩国男性可视人人数据采集工作。（2）美国可视人数据集已在医学教育和临床研究上取得巨大的收益,并提出进一步构建物理人和生理人的思路和实践。（3）人体数字化数据集的科学意义和应用前景。（4）我国于2001年174次香山科学会议揭开了中国数字化虚拟人体研究序幕，解决了关键技术的探索后，已提供了有中国人特色的男性和女性4个数据集的获取工作。

Scientific significance and prospective application of digitized virtual human]

As a cutting-edge research project, digitization of human anatomical information combines conventional medicine with information technology, computer technology, and virtual reality technology. Recent years have seen the establishment of, or the ongoing effort to establish various virtual human models in many countries, on the basis of continuous sections of human body that are digitized by means of computational medicine incorporating information technology to quantitatively simulate human physiological and pathological conditions, and to provide wide prospective applications in the fields of medicine and other disciplines. This article addresses 4 issues concerning the progress in virtual human model researches as the following: (1) Worldwide survey of sectioning and modeling of visible human. American visible human database was completed in 1994, which contains both a male and a female datasets, and has found wide application internationally. South Korea also finished the data collection for a male visible Korean human dataset in 2000. (2) Application of the dataset of Visible Human Project (VHP). This dataset has yielded plentiful fruits in medical education and clinical research, and further plans are proposed and practiced to construct a Physical Human and Physiological Human . (3) Scientific significance and prospect of virtual human studies. Digitized human dataset may eventually contribute to the development of many new high-tech industries. (4) Progress of virtual Chinese human project. The 174th session of Xiangshang Science Conferences held in 2001 marked the initiation of digitized virtual human project in China, and some key techniques have been explored. By now the data-collection process for 4 Chinese virtual human datasets have been successfully completed.
