In Vivo Determination of the Complex Elastic Moduli of Cetacean Head Tissue

Abstract

The overall goal of this project is to develop and demonstrate a system for non-invasive in vivo measurement of the complex elastic moduli (stiffnesses and loss factors) of cetacean head soft tissues. This system is ultimately intended to provide a portable diagnostic capability for use in stranded animal assessments. The primary objective of this project is to develop an ultrasound-based system for non-invasive determination of in vivo shear and bulk properties of cetacean soft tissues, including jaw fats and brain. The ultimate goal is to field a prototype system for examinations of stranded animals. Data collected with this system is intended to provide: 1) basic knowledge of in vivo tissue viscoelastic properties, and 2) a potential basis for diagnostics of tissue pathologies.
