Abstract

The two facts which the roentgenologist must know about a beam of x-rays which he is going to use are its penetrating power and its intensity. The penetrating power of a beam of x-rays produced by any set of technique factors can be determined from charts prepared from the experience of many investigators, including the authors, who have produced a set of 160 charts for that purpose. The charts are drawn actual size and show the distribution of x-rays in water with all the variations in technique commonly used in therapy, - water being used as a medium because the absorption and scattering of x-rays in water is practically the same as in tissue. The use of the charts is simple and direct.
