In vivo CT-based finite element model of echolocation beam formation
Abstract
Synthetic underwater mine-hunting systems have improved dramatically over the last several decades, yet they continue to underperfor,m relative to dolphin mine hunting systems. Emulation of dolphin biosonar processes can potentially improve synthetic mine-hunting s,ystems, as well as augment other acoustic detection systems. The study proposed here addresses the ability of the bottlenose dolphin, (Tursiops truncatus) to form the echolocation beam, which is an acoustic feature that can be adaptively changed in response to envi,ronmental feedback, as well as target detection and identification tasks. Tissue effects will be assessed through Finite Element Mod,elling (FEM) of the bottlenose dolphin head based on in vivo computer tomography (CT) images of a dolphin involved in US Navy bioson,ar research. The outcome of the project will inform Navy interests in processes and mechanisms that can improve underwater target de,tection, localization, and recognition. This project is a collaboration between Lund University (Dr. Josefin Starkhammar) and the Na,tional Marine Mammal Foundation (Dr. Dorian Houser).
