説明
Experiments on the scanographic examination were performed using mechanism of a tube motion of a planigraphic apparatus. A scanographic picture was taken by the contenius motion of a narrow slit which was attached beneath the x-ray tube and was compared with conventional x-ray picture. In the conventional radiograph, as apart from the central beam on the film. The scanographic examination with a planigraphic apparatus indicates the following. This method gives a more corect size of object, resolution test with the grid made of wires size from 0.1 to 0.5 mm was performed. Satisfactory resolution was obtained when the wires of the test grid and the direction of x-ray tube motion were the same, but the test grid set in the direction of right angle or 45 degrees to direction the tube motion showed decreased resolution. In order to determine the true length of bone, the experiment was performed with a metallic rod. The results of the experiment on the effect of slit width of diaphragm on scanography should be taken by x-ray slit light beam within 3 mm on the film.
