1. A computer-supported method for reconstructing an image of a three-dimensional subject comprising the steps of:

  • supplying at least three two-dimensional projections of a three-dimensional subject, onto a projection surface composed of surface elements, to an evaluation computer, said projections being offset from each other by difference angles in a rotational plane;

    in said evaluation computer allocating to each of said surface elements a position designation designating a position of the surface element in the projection surface, and in each projection, a surface data value; and

    in said evaluation computer, allocating binary volume data values, dependent on the respective position designations and surface data values of a plurality of said surface elements, for a plurality of volume elements having respective positions in space, for generating a three-dimensional image of said subject from a totality of said volume elements.
