摘要： A method of X-ray computerized tomography whereby a scanner in which an X-ray source for irradiating an X-ray in a cone-beam shape to an object and a two-dimensional detector for detecting the X-ray transmitted through the object are installed is rotated around the object and a projection angle is changed and a distribution of X-ray attenuation coefficients of the object is reconstructed from the transmitted X-ray images obtained at a plurality of projection angles. This method has the steps of: (1) measuring a first transmitted X-ray image measured in a state in which a contrast medium is injected into the object, a second transmitted X-ray image measured in a state in which no contrast medium is injected into the object, and a third transmitted X-ray image measured in a state in which no object is positioned in the apparatus; (2) calculating a first projection image from a difference between logarithms of the first and second transmitted X-ray images obtained at the same projection angle, calculating a second projection image from a difference between logarithms of the second and third transmitted X-ray images obtained at the same projection angle, and simultaneously reconstructing a first reconstructed image from the first projection image and a second reconstructed image from the second projection image in parallel; and (3) composing the first and second reconstructed images, thereby forming a composed image.

摘要： A method for X-ray computed tomography includes a process for rotating around an object an X-ray source for applying a cone-beam X ray and a scanner having a two-dimensional X-ray detector mounted thereon for deriving projection data and a process for preparing a geometric distortion correction table for correcting an image geometric distortion of the two-dimensional X-ray detector for the projection data, for reconstructing a distribution of X-ray attenuation coefficients of the object from said corrected projection data. The method further includes a process for calculating a function for evaluating the correction table, a process for comparing the calculated value with a threshold value, a process for correcting the correction table through the interpolation based on the compared result, a process for correcting an image geometric distortion of the projection data by using the corrected table, a process for detecting a location of a view field boundary of the detector from the distortion-corrected projection data, and a process for generating the projection data of a predetermined width from the detected location of the view field boundary through the effect of the extrapolation. The method operates to reconstruct a distribution of X-ray attenuation coefficients of the object from the extrapolated projection data.
