(Purpose) This study was attempted in order to demonstrate the use of color film and color intensification in X-radiography as an aid in expressing differences in the density and thickness of the object not only with degrees of contrast but also with changes in color tone in a color X-ray picture. It was felt that this would widen the diagnostic range of X-radiography. (Method) (1) Non-screen method A method of X-irradiation following the placement of color film in X-ray paper casettes or in black paper bags. (2) Color screen method Color intensifying screen was pasted on a casette in order to place the color film in between and X-irradiation was used after sealing this. (Results) Color-X-ray radiography describes differences in the density and thickness of objects or differences between soft tissues and bone by the use of different color tones with excellent contrast and latitude. Since the thick and thin parts of the object are expressed equally in the same picture, a high dissolving power is obtained. (Conclusion) Color film is used to define differences in the fine structures of objects beins irradiated by X-ray and is termed "X-ray color photography."Color intensifying paper has a maximum wave lenght of blue, green, and red, with simultaneous luminescence in response to X-ray atimulation. Through a mixing of the emitting spectrum, color film is sensitized with several kinds of color light. The range of wave lengths is wider than an black and white sensitizing paper. Color X-ray pictures express bones with blue color, cartilage with red color, and areas containing no objects with a color similar to white in order to heighten the contrast. Future research efforts should be made in an attempt to heighten the degree and to improve the color tone of color X-ray photographs.

Not a few fundomental studies of the transversal tomography have been done and also the clinical study was already successful since the tomography was reported in 1929. A good result has been shown by means of removing except the useful beam with a variable diaphragm, the inclined method of grid stripe and the wedge method, in order to keep the skin surface from density and illegibility in this tomography. This paper covers a good result of prevenling the skin surface from density to some extent, the disappearance of the grid stripes in the central part and the removal effect of the scattered X-rays at the same time, as one of the methods.

Measurements of the anteversion of the neck of the femur are fraught with various problems, e. g. simple ones are inaccurate, while elaborate methods necessitate troublesome calculations, and further, lineartomographic method, which make direct measurement, is handicapped with larger exposure of gonads to radiation. Therefore we tried to find a simple and accurate method with less radiation hazards to gonads using Circustomography.

The following shows the calculation of the scattered X-ray quantity with the Electrnic Computer (HITAC 5020), programing in the Fortran term a general expression to require the scattered X-ray which is back-scattered by the scatterer (Pb block) far from the ^<60>Co source and is detected being incident upon the observing point (Detector).
