Abstract:
1. A computer-readable medium encoded with a computer program for operating a computer to control a radiation detector and a display apparatus to: derive a processed image by subtraction processing of a first image derived by a first radiation having a first energy and transmitting through an object and a second image derived successively to the first image by a second radiation having a second energy different from the first energy and transmitting through the same object, among a plurality of images of successive frames detected by the radiation detector detecting as an electric signal the radiation transmitted through the object, wherein each of the processed images is obtained by performing a subtraction process, and wherein the subtraction process is performed between one of odd images and one of even images, and wherein the one of the even image is derived in succession to the one of the odd image, and to display on the display apparatus successively a plurality of the processed images derived thereby.
