Title:
RADIATION TOMOGRAPHY
Document Type and Number:
WIPO Patent Application WO/2010/073308
Kind Code:
A1
Abstract:
A radiation tomography includes a step of calculating a transformation function from a transmission image captured by using radiation emitted from a first radiation source and a transmission image captured by radiation emitted from a second radiation source. The position of the second radiation source of when a second calibration radiation is emitted is the same as the position of the first radiation source of when the first calibration radiation is emitted. When either the first or second radiation source emits radiation, the other also emits radiation. The radiation tomography further includes a step of capturing first reconstruction transmission images and second reconstruction transmission images by using the first reconstruction radiation and the second reconstruction radiation simultaneously emitted from the first radiation source and the second radiation source respectively, a step of correcting the first and second reconstruction transmission images according to the transformation function into corrected transmission images, and a step of reconstructing three-dimensional data from the corrected reconstruction transmission images.
