With a certain kind of planagraph apparatus there in an inevitable prolongation of the time of projection with changes in the transversal angle. The calculation has been difficult and has been apt to depend on experience and intuition. Therefore, the author with a stroboscope measured the time of projection and the exect incidence angle of each transversal angle and calculated energy of X-ray putting all the results together to make a simple and practical exposure chart for planagraphy.
