Research Interest

Dr. Jinyi Qi’s research focuses on developing advanced signal and image processing techniques for molecular imaging. One emphasis is on developing statistically based image reconstruction methods for emission tomography. The research involves modeling imaging system response, developing appropriate statistical models, developing optimization algorithms, and analyzing image properties. Current projects include high-resolution image reconstruction, adaptive PET imaging, dynamic PET data analysis, image quality evaluation for system optimization, and information fusion in multimodality imaging.
