Shigeo Satomura (1919 – 1960) was a Japanese scientist.
Together with Ziro Kaneko, he constructed the Doppler flowmeter to measure the Doppler noise from blood vessels.
Satomura worked with Yoshida and Nimura to assess the motion of the walls and valves of the heart and developed the transcutaneous noninvasive Doppler flowmeter in 1958. Then with Prof Kaneko to study blood flow in the human brain in cases of dementia (to differentiate the Alzheimer variety from those of cerebrovascular origin) with the ‘ultrasonic blood rheograph’
- Born 1919, Osaka Japan

- Satomura Doppler flowmeter
- Satomura blood-rheograph
- Satomura Ultrasonic Doppler Cardiograph
When an ultrasonic beam is radiated into the blood vessel by a transducer placed on the surface of the skin, the reflected waves are produced from the blood-flow. Hence they can be detected as a kind of tone by means of a sensitive receiver. Because the intensity and the frequency character of this tone is proportional to the velocity of the bloodflow, it is possible to investigate the behaviour of the bloodflow through this method.Satomura 1959.
Key Medical Attributions
- 1955 – investigated the use of microwave and ultrasound to measure vibrations in wooden boards. Applied these ultrasound research principles to aid medical diagnosis. Worked with cardiologists T. Yoshida and Yasaharu Nimura at the Osaka University Hospital to measure heart motion and pulsations of peripheral blood vessels and eye vessels.
- 1955 – Published “A new method of the mechanical vibration measurement and its application” demonstrating that doppler signals can be retrieved from heart movements when insonated with 3 MHz ultrasonic waves
- 1960 – Completed studies and papers on the “Ultrasonic Doppler Cardiograph” and “Ultrasonic blood rheograph”.
