Dr. Shinji Takahashi was the first to advocate the basic concepts of CT in the 1950’s, and is a pioneer that Japan boasts about to the world. He constructed slice images by recording a sinogram of cross sections of parts of a human body onto a film and implementing optical back projection. CT imaging by Hounsfield, who won the Nobel Prize in 1978, was introduced in 1972, and Dr. Takahashi’s research work precedes it by 15 years. His detailed achievements are recorded in his English book titled “Rotation Radiography”, published by the Japan Society for the Promotion of Science in 1957. In praise of his magnificent work, in the 2012 issue of the English journal, “Radiological Physics and Technology”, we put his picture on the cover and summarized his life and achievements as an editorial article.

Moreover, in the field of radiotherapy, Dr. Takahashi is also known as the founder of IMRT, who invented conformation radiotherapy in the 1960’s. He was born in 1912 in Nihonmatsu city, Fukushima. After graduating the Medical Department at Tohoku University, he held successive posts as a professor at Hirosaki University and University of Nagoya, the vice president of Hamamatsu University School of Medicine, and the president of Aichi Cancer Center.
