FIELD: instrument making.
SUBSTANCE: invention can be used for reconstruction of computer tomography image. Invention consists in that it comprises performing an image forming scanning wherein L consecutive angles of projection are measured at low energy x-ray beams and n consecutive angles of projection are measured at high energy x-rays alternating manner, where L is considerably less than n, to generate data set of projection of low energy, comprising measuring angle of projection at low energy and high energy projection data set containing measuring angle of projection with high energy; estimation of sub-sampled part of projection data set at low energy in order to generate estimated full dataset projection at low energy, low-energy estimation is performed without image reconstruction of data set of projection of low energy or data set of projection of high energy.
EFFECT: technical result is improved quality of obtained image.
