Evaluation of the accuracy and precision of ultrasound attenuation slope estimates
New approaches in the field of ultrasound utilize the frequency content of the backscattered signal, which contains information about the scattering tissue structure and enables quantitative ultrasound imaging. The ultrasonic attenuation is a quantitative parameter that can be used to characterize …

The state of the art time-domain wavefield imaging using a discontinuous Galerkin forward-backward time-stepping method
In this thesis, an efficient wavefield imaging technique of Forward/Backward Time-Stepping (FBTS) in the Time Domain (TD) is developed, employing the Discontinuous Galerkin Method (DGM) as the spatial-discretization technique. The FBTS method is based on calculating gradients of a TD cost …

Non-contact quantitative imaging of limbs, bone and tissue, using ultrasound tomographic techniques
Non-contact and quantitative ultrasound images of bone and soft tissue are produced from original algorithms applied to observational data sets collected on two custom built ultrasound imaging systems for limb imaging. The images are quantitative in that the distribution of sound speeds and …

The Mechanism of Action of Hyaluronan Therapy as a Treatment for Osteoarthritis and the Assessment of Osteoarthritic Articular Cartilage Using Ultrasound
… early and to treat effectively. Existing imaging techniques often only detect osteoarthritic damage after substantial structural loss has occurred. This thesis investigates two key aspects of OA management: (1) how hyaluronan (HA) therapy interacts with articular cartilage at the molecular …
