Title: RADIOGRAPH AND IMAGE PROCESSING PROGRAM
Abstract:
A radiograph comprises an X-ray source for emitting X-rays with a first energy spectrum and X-rays with a second energy spectrum, an X-ray detector for detecting X-rays with the first energy spectrum having passed through a subject and X-rays with the second energy spectrum having passed through the subject and outputting projection data on the first energy spectrum and projection data on the second energy spectrum, control means for controlling the operation of the X-ray source and the X-ray detector, image processing means for creating a desired image from the projection data on the first energy spectrum and the projection data on the second energy spectrum, and display means for displaying the image. The radiography is characterized in that the image processing means has acquiring means for acquiring the projection data on the first energy spectrum and the projection data on the second energy spectrum, synthesis image creating means for combining a first image formed from the projection data on the first energy spectrum and a second image formed from the projection data on the second energy spectrum under a predetermined combining condition, and synthesizing a synthesis image and that the display means displays the synthesis image.
