FIELD: physics.
SUBSTANCE: application: for reengineering of three-dimensional image by means of scanning by rectilinear trajectory. It consists in the fact that image reengineering at three-dimensional stereography is carried out by means of application of scanning by rectilinear trajectory, with transformation of projected data from scanning by rectilinear trajectory into projected data from scanning with quasi-parallel beam, and also by execution of filtration with obtainment of filtered projected data by means of compression of projected data from scanning with quasi-parallel beam with preliminarily determined nucleus of compression, afterwards reverse projection is carried out for reconstruction of image by means of reverse projection with weight coefficient of filtered projected data.
EFFECT: increase of scanning rate at three-dimensional stereography.
