Title: IMAGE DISPLAY CONTROL DEVICE, X-RAY CT DEVICE, AND IMAGE DISPLAY METHOD
Abstract:
The purpose of the present invention is to improve the readability of feature amounts for various types of images obtained by multi-energy imaging. Provided is an image display control device (200) comprising: a storage unit (123) for storing images of various types obtained by emitting X-rays with two or more different energy intensities and association information in which the images of various types are associated in accordance with a predetermined condition; a region setting unit for setting a region of interest for an image among the images stored in the storage unit (123) and for images associated with said image by the association information; a feature amount calculation unit for calculating a feature amount indicating a feature of the images for each of the associated images on the basis of a pixel value of the region of interest; a patterning processing unit (126) for generating a gradation pattern in which the difference between the associated images in the feature amount is expressed by gradation or variation of a predetermined color; and a display unit (125) for displaying the gradation pattern together with said image and at least one of the images associated with said image.
