摘要
目的根据球缺体积公式推导出计算颅内血肿体积的改良公式,提出更为准确的计算方法。方法根据血肿形态类型,采用立体几何中球缺的体积公式,推导出计算颅内血肿的改良体积公式,以计算机软件测得血肿体积作为相对准确的标准,将改良体积公式和多田氏公式计算的血肿体积值分别与之进行比较。结果改良体积公式计算与软件测量结果的差值明显小于多田氏公式计算与软件测量结果的差值。结论颅内血肿改良体积公式较多田氏公式的计算结果更为准确,可以用于法医学鉴定。
Objective The more accurate calculate method was investigated according to the improved formula of intracranial hematoma using segment deducing.Methods The improved formula was deduced to calculate the intracranial hematoma using the volume formula of the solid geometry.The volume of intracranial hematoma was measured as a related accurate standards using software.The volumes of intracranial hematoma calculated by the improved formula,Tada’s formula and the software were compared.Results The measure accuracy of the improved formula was higher than that of Tada’s formula,and showed a similarity with that by using software method.Conclusion The improved formula method shows a more accurate result than Tada’s formula,and can be used in forensic practice.
