Learning Post-Stroke Gait Training Strategies by Modeling Patient-Therapist Interaction
Lower-extremity hemiparesis, characterized by weakness or partial paralysis on one side of the body, significantly impacts a vast majority of stroke survivors. As a result, physical therapy intervention is crucial for the successful recovery and rehabilitation of a patient's gait cycle. During these sessions, physical therapists implement corrective...

Electronic Fringe Scanning for the Improvement of Medical Imaging Technology
This technology includes an electronic method for fringe scanning in grating-based phase-contrast imaging, which enhances x-ray phase-contrast imaging. Traditional methods use high-density gratings and require fine grating fringes, finer than the detector's resolution, necessitating fringe scanning to obtain phase-contrast information. This process...
