Description

Excerpt from The St. Louis Medical and Surgical Journal, Vol. 86: January-June, 1904 Position OF the tube - The position of the tube is Of very little importance. The majority of physicists believe that the rays are thrown at right angles from the anodal plate, and claim that the most active portion of the tube is the center of the phosphorescent hemisphere. I believe, however, that the rays within the tube are equal in all directions. The position Of the tube in the treatment Of such conditions as carcinoma of the cervix, disease Of the oral cavity, larynx, stomach or rectum is a difficult matter. If the tube be placed within the cavity or in such a position as to send the rays directly to the diseased area, better results are Obtained than if the rays must first penetrate the intervening tissues. For this reason special tub es have been devised by Caldwell of New York and Cossar Of London for the treatment Of disease Of the rectum. Vagina and mouth. The Caldwell tube consists of a long, cylindrical projection which fits into a metallic protector; the latter has an opening which corresponds to the area to be treated. The Cossar tube is made of lead glass, which is comparatively Opaque to the X-rays, excepting at the end of the projection, which, being made from ordinary glass, allows the rays to reach only the diseased area.
