Ultrasound Ultrasonic Guided Waves Guided Waves Human Health Monitoring Fifth Metatarsal
Abstract:
Qualitative ultrasound (QUS) has become a promising human health monitoring method,
especially in analyzing long cortical bone, skull phantoms, and even the metatarsals. In QUS,
guided waves can be used as a method of long-range scanning by using the human bone as an
active waveguide. Typical fracture diagnosing methods, such as X-ray and Computed Tomography
(CT) scanning are often avoided in excess due to their invasive behavior, high costs, and chance
for possible human error. Before QUS is employed for fracture detection, the complex geometry
of the bone waveguide must be studied. This thesis will aim to specifically analyze the fifth
metatarsal and investigate ultrasonic wave phenomena as waves propagate axially down the
waveguide. The bone will be modeled as more simple geometry, and finite element analysis (FEA)
will be used to study common wave modes at particular frequencies. Finally, a 3D printed material
that mimics the cellulose fiber in bone material will be investigated to see if it can be used as a
potential surrogate for physical bone modeling.
