Attachment mechanisms of a novel, targeted, lipid-based, ultrasound contrast agent
… of a novel, targeted, lipid-based, microbubble ultrasound contrast agent (UCA) for assessment of coronary heart disease (CHD) with high frequency intravascular ultrasound (IVUS). The targeting mechanisms assessed for microbubble attachment include a streptavidin-biotin mechanism, electrostatic …

Quantitative Ultrasound Characterization and Monitoring of Locally Advanced Breast Cancer
… clinically significant. In this thesis, novel ultrasound backscatter signal analysis and machine learning techniques were developed to characterize breast tumours and detect early changes correlated to response. In the first study, tumour cell death was induced in human breast cancer …

Effect size estimation and robust classification for irregularly sampled functional data
… data from inter-laboratory quantitative ultrasound measurements, and in a reanalysis of Canadian weather data. Moreover, we represent the asymptotic power of functional ANOVA test as a function of proposed measure. The agreement between the asymptotic and empirical results is examined and …

Quantitative ultrasonic characterization of diffuse scatterers in the presence of structures that produce coherent echoes
Quantitative ultrasound (QUS) techniques that parameterize the backscattered signal power spectrum have demonstrated significant promise for ultrasonic tissue characterization. Some QUS parameters, including the effective scatterer diameter (ESD) and the effective acoustic concentration (EAC) that …

Improved Techniques for Statistical Analysis of the Envelope of Backscattered Ultrasound Using the Homodyned K Distribution
Biomedical ultrasound is a prominent imaging modality for diagnostics. Conventional ultrasonic imaging is qualitative in nature with spatial resolution up to hundreds of micrometers. Quantitative ultrasound techniques based on ultrasonic backscatter can provide estimates describing tissue …

Using two-dimensional impedance maps to study acoustic properties of tissue microstructure
Quantitative ultrasound (QUS) imaging represents a set of techniques for estimating acoustic properties of tissue microstructure that have confirmed potential for identifying disease and monitoring therapy. In one approach to QUS, the backscatter coefficient (BSC) from a tissue is utilized to …
