A Systematic approach to improve Support Vector Machine applied to ultrasonic guided wave spectrum image classification
(IEEE, 2021)Osteoporosis is a skeletal disorder characterized by low bone mass, which compromises its resistance and increases the risk of fractures, and is a widespread problem worldwide. Currently, the gold standard for assessing ... -
Extraction of the First-Arriving-Signal and Fundamental Flexural Guided Wave Using a Radon Transform Based Approach Applied to Ultrasonic Characterization of Cortical Bone
(IEEE, 2021)Ultrasonic guided waves have been used for characterizing cortical bone. However, multimode ultrasound signals bring difficulty in signal processing, making it challenging to extract the first arriving signals (FAS) and ... -
Real Time Waveguide Parameter Estimation Using Sparse Multimode Disperse Radon Transform
(IEEE, 2021)Osteoporosis and associated fragility fractures are still a societal problem. Several quantitative ultrasound approaches have been proposed to overcome limitations of the current gold standard DXA. Bi Directional Axial ... -
Selection of Bone fragility-Related Features Obtained with Bi-Directional Axial Transmission, Through a Machine Leaming Strategy
(IEEE, 2021)Osteoporosis is a widespread public health problem worldwide, characterized by low bone mass, which compromises strength and increases the risk of fracture. Currently, the gold standard for assessing fracture risk is ...
