Research

My doctoral research was focused on ultrasound parametric imaging on liver tumors using clinical scanners, including projects on scatterer size and attenuation imaging, ultrasound elastography, image segmentation and registration. Currently I am working with Dr. Lei Xing on image guided radiotherapy.
