If the early stages of a disease begin with the involvement of a
small area of cells or tissue, the early diagnosis of pathologic
changes by means of radio graphy should concentrate first on the
detection of such minute changes. The ideal solution would be to
produce X-ray images of findings much finer than those observable
by the naked eye, and herein lies a new field of research that is
believed to be worth developing. The introduction of a 0.3 mm
focal-spot rotating-anode tube about 25 years ago opened the way to
the clinical application of magnification radiography. Due to the
postwar economic situation, we were unable to import this type of
X-ray tube, but we believed in the importance of magnification
radiography in X-ray diagnosis, and in 1952 we produced an X-ray
tube with a 0.15 mm focal spot by reconstructing an existing
fixed-anode tube. This X-ray tube has been improved step by step,
so that tubes with focal spots of 0.1 mm or 0.05 mm are now
available in Japan. Thus it has become possible to obtain 4 to 6 x
magnification images of minute lesions that could not be imaged by
normal roentgenography."
