Abstract: With the development of the Internet+, medical big data is showing explosive growth which has multitudinous data types and complex relationships. The general data visualization method is difficult to demonstrate medical big data effectively, the medical big data visualization technology faces the huge challenge. This paper outlines the origin, characteristics and research progress of medical big data, introduces the related concepts and research status of visualization of medical big data. The existing visualization methods of medical big data are studied and divided into 2 types, which give a comprehensive description of the characteristics, legend and common visualization methods of medical big data by using a table. Future research focuses and problems of visualization of medical big data are analyzed and also have important reference value in research methods and universal application of visualization of medical big data.

Key words: medical big data, visualization of big data, Internet+

摘要： 随着“互联网+”的迅速发展，医疗大数据不仅数据类型繁多、关系复杂，且呈爆炸式增长，一般的数据可视化方法难以对其进行有效的展示，医疗大数据可视化技术面临巨大挑战。概述了医疗大数据的起源、特点及其研究进展，介绍了医疗大数据可视化的相关概念及其研究现状，将现有医疗大数据可视化方法划分为两大类，分类阐述了常见的医疗大数据可视化方法，给出了包括分类、图例、特性的可视化方法比较一览表。最后分析了医疗大数据可视化中存在的问题，指出其未来研究重点，对医疗大数据可视化方法研究与普及应用具有重要的参考价值。
