IMAGE ACQUISITION DEVICE, IMAGE ACQUISITION METHOD, AND IMAGE CORRECTION PROGRAM.

摘要

Provided are an image acquisition device and an image acquisition method that allow the internal and external contours of a measured object to be acquired with a high level of precision. An image acquisition device 1 is provided with: a first X-ray source 10, which radiates X-rays having a first focal point size; a first detector 20, which detects X-rays radiating from the first X-ray source 10 that have passed through a measured object O; a first image generation means 30, which generates a first X-ray CT image on the basis of the X-rays detected by the first detector 20; a second X-ray source 40, which radiates X-rays having a second focal point size, which is smaller than the first focal point size; a second detector 50, which detects X-rays radiating from the second X-ray source that have passed through the measured object O; a second image generation means 60, which generates a second X-ray CT image on the basis of the X-rays detected by the second detector 50; and an image correction means 70, which corrects the first X-ray CT image generated by the first image generation means 30 on the basis of the second X-ray CT image generated by the second image generation means 60.
