- 摘要：
To achieve both reduction of radiation dose when photographing a low-dose radiation image used for image processing and improvement of image quality of the low-dose radiation image used for image processing.
SOLUTION: (A) shows a frequency distribution acquired after logarithmic conversion of Fig.3 (A), in which low-dose values in a range necessary for energy subtraction processing are missing. Next and an example is presented in which the minimum value of a recording range is moved to the low-dose side. (B) shows a frequency distribution acquired after logarithmic conversion of Fig.3 (B) in which the minimum value of a recording range is set at a smaller value and in which a range necessary for energy subtraction processing is almost included.
