<p><P>PROBLEM TO BE SOLVED: To provide an image display device which outputs information for achieving both detailed analysis and rough material discrimination relating to the material discrimination in the image of a subject, on the basis of an image obtained by dual energy imaging. <P>SOLUTION: The image display device includes: image acquiring means for acquiring first and second images Gw, Gio mutually different in correspondence relation between a material and a pixel value; scatter diagram generating means for generating a scatter diagram Gg1 where points corresponding to the pixel values of respectively mutually corresponding pixels in the images Gw, Gio are plotted in a coordinate space Kwi where the pixel value Wg in the first image Gw is defined as a horizontal axis and the pixel value Ig in the second image Gio is defined as a vertical axis; storage means for storing plot ranges Rc, Rio, ... to be estimated to indicate prescribed respective materials when the points corresponding to the pixel values of the mutually corresponding pixels in the images Gw, Gio are plotted in the coordinate space Kwi; and display means for displaying the scatter diagram Gg1 and the plot ranges Rc, Rio, ... by superimposition. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
