Forensic volumetric visualization of gunshot residue in its anatomic context in forensic post mortem computed tomography: Development of transfer function preset

نویسندگان

چکیده

While the visualization of gunshot injuries so far focused on solid metal density in routine forensic post mortem computed tomography (PMCT) as well micro-computed tomography, residue (GSR) dispersed particles typically succumbs to partial volume effect. A case series seven contact shots head was evaluated determine a range for GSR with at least three times higher likelihood than encountering bone, skin, muscle or blood. For that, Bayesian determined from normal distributions CT-densities blood, and identified correlation visual evidence. Resulting transfer functions matched ring cone shaped deposits published elsewhere, thus representing plausible result. Only fast plausibly specific is suitable use PMCT, allow examination real cases wider scale.
