ABSTRACT:
A very fast reconstruction is undertaken in an image reconstruction process by tomography, by dividing measurements through the subject into a series of subsequent sets that are inverted by back projections giving partial result blocks used to search for the change law for the subject. Partial contents of the image can then be predicted at a reference time and their accumulation gives the image. The law for how the subject changes with time is evaluated and is used to compensate for partial results before their accumulation.
