Research

当グループでは、生体や細胞を操作し環境を変化させるツールとして音響波を用いることを目的とし研究を行っています。音響工学と光工学に基づき、これまでに独自の音響波発生装置や変調器を提案・実現しています。また、音響波と生体との相互作用を明らかにするため、最先端の超高速イメージング技術を開発しています。 

• Sound-cell interaction

• Acoustic-optical techniques for investigating deep brain area

• Imaging technologies for clinical sites

• Ultrafast imaging
