An exact scheme for dynamical HOLZ calculations has been developed with a matrix formula based on the modified Bethe's theory and current flow without the small angle approximation. The HOLZ intensity must be calculated with the current flow for electron beams. For a quantitative intensity calculation at large illumination, not only the current flow in diffracted beams from an exit surface but also the current flow in a primary beam plays an important role.
