Abstract
A diagnosis apparatus using an X-ray CT includes an X-ray scanner for repeatedly scanning a single portion of a subject using an X-ray a plurality of times to output X-ray projection data, an injector for injecting a contrast medium into the subject, a data collecting device for collecting the X-ray projection data output from the X-ray scanner, an image reconstruction device for reconstructing the collected data to generate reconstructed image data, an image analyzing device for analyzing the image data obtained by the image reconstruction device to calculate parameters each representing a state of permeability of blood vessels, a computer for combining the parameters to form diagnosis images, and a display for displaying the diagnosis image.
