Wave information systems Laboratory

Seeing with sound, diagnosing with sound

 
We are studying methods to obtain information inside our body by using high-frequency sound waves, which cannot be heard by the human ear. At hospital, doctors frequently make a diagnosis by using ultrasonic diagnosis apparatuses. Our main goal is to establish the basis for next-generation diagnosis apparatuses, in addition to ultrasonic microscopes for diagnosing biological tissues with sound waves. Studying this field requires a broad knowledge of software and hardware, but it makes our study all the more interesting.

For Society

Ultrasonic Doppler flowmeters, used at hospitals for observing blood flows, often erroneously detect high-speed blood flows. The broadband Doppler method that our laboratory developed can solve this problem. We are in the midst of our efforts to make it for practical use.
