Forensic Case Analysis: From 3D Imaging to Interactive Visualization Forensic case analysis: from 3D imaging to interactive visualization

Recently forensic investigators have shown an increasing interest in the bene-fits of 3D medical imaging modalities to improve forensic case analysis by en-abling observation of body interior. While Computed Tomography (CT) allows excellent depiction of bony structures, Magnetic Resonance Imaging (MRI) provides good contrast in soft tissue structures and involves no exposure to harmful radiation. We present an integrated, interactive framework to aid forensic investigators in case analysis and courtroom presentation tasks. Our framework makes extensive use of advanced computer graphics and computer vision techniques and is implemented entirely on the GPU. It enables a forensic analysis work-flow from the raw data, over segmentation techniques to enhance structures of interest, to the presentation via focus and context enabled multi volume rendering techniques, resulting in interactive scenes, videos, or images suitable for the courtroom. Two selected case studies demonstrate the practical applicability of our framework on real forensic cases
