Abstract: Craniocerebral injury Identification is important and tough in forensic medicine practice. There are some deficiencies in traditional biomechanical analysis， such as obsolete methods and ambiguous data. Virtual autopsy and finite element analysis， which are based on imaging examination techniques， show many advantages including noninvasive imaging， sufficient detail and nicety mechanical data. So the introduction of these digital techniques might improve the objectivity of evidence documentation and promote the development of forensic science.

Key words: craniocerebral injury, biomechanical analysis, imaging technique, finite element

摘要： 颅脑损伤是法医学鉴定的重点和难点，传统的颅脑损伤生物力学分析存在技术手段陈旧、分析数据模糊等问题。基于影像学的虚拟解剖技术和有限元分析技术具有非侵入、细节还原充分和力学数据准确等优点，在颅脑损伤生物力学分析中引入先进的数字化技术可提高鉴定证据客观性，推动学科的发展。
