PURPOSE: To provide a novel three-dimensional image reconstituting method enabling the speedup of the reconstitution of a three-dimensional image and the sharpening of the image and apparatus therefor. CONSTITUTION: In a method for reconstituting a three-dimensional image of matter M defined as a function of a plurality of points, the function is present as the conical radiations 5, 5' transmitted through the matter M having a focus and calculated as the sum total of the functions of the surface passing at least one point of the matter and limited as a matter reference frame to contain at least two series, and the sum total of the functions of the above surface is calculated on the basis of at least one series of measurement. A series of measurements is executed by the two-dimensional arrangement of an irradiation sensor and a track has centers 01, 02 and defined in the same way as the matter with respect to the matter reference frame and a series of function sums is calculated as each series of measurements in the matter reference frame and series are pooled in order to obtain the sum of functions in the reference frame. |
