FIELD: physics.
SUBSTANCE: claimed invention discloses the high-resolution image data. This process includes the step whereat radiation source is controlled by the controller for modulation of emitted radiation between high and low flow during different integration period at one scanning. Besides, in compliance with this process, high-resolution images are constructed on the basis of high-resolution projection data obtained with insufficient quantisation step during high flow and incomplete low-resolution projection data obtained during low flow.
EFFECT: decreased radiation dose at scanning by computer tomography.
