Under kind permission of his daughter, Ms.K.K., this paper is presented as a menory of his activity in medical engineering in Japan. Figures and references were not given, but references given in the Japanese version will be useful.

"From Cell Counting to Radiology " by Hiraku MATSUEDA M. D.

A WORD OF ACKNOWLEDGEMENT AND RECOMMENDATION
Doctor Hiraku Matsueda is a pioneer in the field of Medical Engineering in Japan. His studies based on a broad field of vision are now generally recognized. My own present thesis was written contemporaneously with the development of his thesis, and along the line of his way of thinking. In the light of such a circumstance, I do hope that the thesis reveals the importance of at creative idea with which the investigator develops his own idea. As a friend of Doctor Matsueda I want to express my deepest respect for him, as well as my confidence on his endless progress.
