Application of a Photoacoustic Tomography System: A Case Study on the Monitoring of Pig Tissue Decomposition

Pig carcasses have been used in forensic research because they share several similarities to human cadaver, including decomposition. In studies, the decomposition of pig’s cadaver for a certain time can be as model determine death human. This study was conducted relationship between days spoilage pig tissue and level average sound intensity produced by sample. Then, this study, skeletal muscles were allowed decay with variation 1–5 days. Afterward, these imaged using diode laser-based photoacoustic tomography. Results experiment show that acoustic from first day until fourth has increased (78–92 a.u young 76–86 old pig) but decreased on fifth (88 84 pig). These results improve imaging such applied plotting ratio sample number
