The Effects of Time and Moisture on Elasticity Imaging Phantom Physical and Mechanical Properties: A Pilot Study
.
Abstract ─ Elasticity imaging phantoms are used to mimic human tissue as a means of testing and validating non-invasive techniques for measuring mechanical properties of human tissues. Limited studies of phantom stability have shown that phantom stiffness change over time when exposed to air. The goals of this study were to investigate how the physical and mechanical properties of elasticity imaging phantoms change with time and moisture state.Two moisture states were tested; a dry state where the phantom was exposed to open air and a wet state where the phantom was submerged in water for 480 minutes. Polyvinyl alcohol (PVA) phantoms (cylindrical shape) were used. The properties of the phantom were found using flat indentation tests and a t... Ver más
