Ryusuke Nakai
My research focuses on the development of image acquisition, image analysis, and biological simulation methods to analyze the functions of biotissue (brain, nerve, muscle, joint, etc.) with more precision using MRI and medical imaging. In the future, I aim to apply these methods to medical and rehabilitation support.
