Thermal ablation and hyperthermia remain as potent treatment options for cancer. However, the inability to closely monitor temperature elevations from thermal therapies in real time continues to limit clinical applicability. Therefore, the development of new imaging techniques capable of providing feedback and temperature monitoring is highly medically significant. In this study, quantitative ultrasound...
Although thyroid cancer has relatively good prognosis, the management of this disease is complicated by the large incidence of thyroid nodules in the adult population. Unfortunately, current imaging methods do not provide a sufficient level of accuracy in order to replace biopsy as a tool for diagnosis of thyroid cancer. A relatively recent study suggests that spectral-based quantitative ultrasonic...
Conventional ultrasound B-mode imaging is mainly qualitative in nature. While conventional imaging techniques, including ultrasound, may be sensitive to the detection of anomalous tissue features, the ability to classify these tissues often lacks specificity. As a result, a large number of biopsies of tissues with suspicious image findings are performed each year with a vast majority of these biopsies...
Quantitative ultrasound using backscatter coefficients (BSCs) is a potentially powerful tool for estimating microstructural properties from tissues. However, most scattering models assume distributions of identical scatterers even though actual tissues exhibit different levels of spatial variations. It has been experimentally demonstrated that the use of single-size scattering models may yield effective...
