Objective To explore the effectiveness of virtual autopsy-based postmortem computed tomography(PMCT)liver three dimensional slicer(3D slicer)artificial intelligence(AI)volume reconstruction to assist forensic practice.Methods Twenty cases of the deceased who underwent both virtual autopsy and traditional autopsy in our center were selected and subjected to liver volume segmentation by 3D slicer method,Tada's formula method and literature method,and the data obtained from the traditional autopsy were compared and analyzed to obtain the accuracy rate.Results The 3D slicer method yielded higher consistency(95%confidence interval),lower volumetric variability(standard deviation),and a smaller region(variance)of uncertainty than the Tada formula method and the methods mentioned in the literature.Conclusion 3D slicer AI reconstruction based on virtual autopsy can visualize virtual anatomy,help increase the diagnostic accuracy of traditional autopsy,assist in pathological diagnosis,and provide new directions and tools for the development of imaging histology of virtual autopsy.
