X-RAY MEASURING METHOD AND POLAR DIAGRAM MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To highly reliably perform measurement by resolving incorrectness in measurement based on fading phenomena which a stimulable fluorescent materials possess in the case of performing measurement through the use of the stimulable fluorescent material in a polar diagram measuring method and other X-ray measuring methods. SOLUTION: Different locations of the stimulable fluorescent material 2 is irradiated with X-rays R1 emergent from a sample S according to a predetermined timing pattern to accumulate data at each location. The data is corrected on the basis of the change characteristics with the passage of time of the energy holding characteristics of the stimulable fluorescent material 2, and the intensity distribution of X-rays is obtained on the basis of the data after the correction.
