Figure 3. Photograph illustrates the technique of thymic irradiation for either status thymicolymphaticus or thymic asthma. In the caption for the original illustration, note was made that a piece of lead rubber sheeting normally covered the restrained infant, except for a window over the thymus. In this photograph, the sheeting was not present to demonstrate the "relation of the cone to the chest." (Reprinted, with permission, from reference 32.)
