摘要： The medical imaging diagnosis apparatus includes: a region-of-interest setting unit configured to acquire an image of an examination target region in the body of a subject, and thus to set up, on the image, a region of interest, in which change in concentration of a contrast medium is observed; a calculator configured to calculate an average of CT values each representing the concentration of the contrast medium in the region of interest; an approximation unit configured to find an approximation for the region of interest on the basis of multiple CT values calculated by the calculator for the region of interest; and a comparison unit configured to compare a coefficient of the approximation with a value representing a setup condition beforehand stored, and to detect the timing of a definitive scan on the basis of the approximation which agrees with the setup condition within a predetermined range.

摘要： An unevenness inspection method for inspecting presence of unevenness in a panel material, the method includes: acquiring a plurality of primary images by imaging the panel material under inspection on a plurality of levels of condition; creating a plurality of secondary images by processing the plurality of primary images to enhance variation of the image; creating a composite image by combining the plurality of secondary images with a prescribed weighting; and determining the presence of unevenness using the composite image, the prescribed weighting being determined so that a region having the unevenness can be distinguished from the other region, when the plurality of secondary images are created for the panel material for training use having unevenness and are combined into a composite image.
