Abstract: PURPOSE:To make measurement to improve the S/N of an energy difference image by forming X-rays having the photon energy slightly higher than the font energy at the absorption end of a noticed element and executing photographing without the noticed element filter by using these X-rays. CONSTITUTION:Both of the X-rays having the photon energy slightly higher than the energy at the absorption edge of the element of interest and its third harmonic are formed by X-ray energy selecting means 2, 8. The X-ray image photographed without using the filter 4 for the element of interest and the X-ray image photographed by making use of the filter 4 for the element of interest are measured. Arithmetic processings 18 to 24 for the energy difference are executed by using such data. Consequently, the photon energy component higher than the photon energy component at the absorption edge increases about two-fold. On the other hand, the measurement with the filter 4 for the element of interest is executed by simultaneously forming third harmonic without loosing the component. There is no adverse influence on the drawing power of the element of interest even if noise removal processing, such as smoothing, is applied when the X-ray intensity is weak and statistical noise is large. A measurement improving the S/N of the energy difference image can be executed in this way.
