Ziro Kaneko

Prof Ziro Kaneko (1915 – 1997) Japanese neuropsychiatrist.

Pioneer in the field of Geriatric Psychiatry in Japan. Together with Shigeo Satomura, he constructed the Doppler flowmeter to measure the Doppler noise from blood vessels.

Kaneko continued work on the flowmeter after Satomura’s premature death in 1960. Although initially they believed turbulent flow was responsible for the recorded flow patterns but in 1962 they concluded that reflections from red blood cells moving at different velocities was responsible, leading to spectral flow analysis

Medical Eponyms

  • Doppler Rheograph – built and marketed by NEC (Nippon Electric Company)

Ultrasonic waves are transmitted to the blood vessels from the surface of the skin and, by demodulating and amplifying the reflected waves that are produced by the turbulent flow within the blood stream, a noise is obtained that changes its intensity in proportion to the velocity of flow of the blood. It is thus possible to determine the state of the blood flow in the arteries and veins and to judge the condition of the blood vessels…
