When we look at the history of Toshiba medical equipment, the word "first" often reappears. Toshiba was the first in Japan to begin research on X-ray tubes in 1914, and has continued to be a national leader in diagnostic imaging equipment, being the first to introduce many products, including MRI and helical CT. We are continuing to write new pages in the history of medical equipment development.
