Improvement of the accuracy of postmortem interval estimation equation using autopsy findings and spectrophotometric values

死后时间估算是法医学研究的重要内容之一。死后现象，如尸体尸斑，尸体僵硬，体温等被用来估计PMI。我们研究了器官重量与PMI的关系。我们提出了一个计算器官重量的公式，使用几个尸检结果等等。当我们考虑PMI时，方程的准确性得到了提高。然而，使用器官重量和一些尸检结果计算PMI的公式的准确性较低，因此需要进一步研究。

Estimation of postmortem interval (PMI) is one of the most important matter for forensic medicine. Postmortem phenomena such as postmortem lividity, rigor mortis, and body temperature and so on are used to estimate the PMI. We studied on the relationship between organ weights and PMI. We proposed an equation for calculating the organ weights using several autopsy findings and so on. When we take into consideration the PMI, the accuracy of the equation was improved. However, the accuracy of the equation for calculating the PMI using organ weights and some autopsy findings waslow to use in practice, so further study is needed.
