ounded by five other rooms which are 790 The Scientific Basis of Short Wave-Length Therapy used lor treatments and for laboratoryinvestigations. The x-ray tubes hang oppo-site holes in the walls and ceilings, throughwhich the rays pass and which contain thevarious filters, etc. The patients to betreated lie on mattresses on the floors ofthe rooms above the x-ray room, or on atable in the room alongside of the x-rayroom. With this arrangement, no odor ornoise can be perceived in the room wherethe patient lies. In fact, he does not know one of the standards used to calibrate thesmaller chambers. The galvanometer andbattery, etc., rest on the shelf in the corner.Figure 14 is a photograph of the patientsbed in one of the treatment rooms abovethe x-ray room. One section of the bed con-sists of a wooden framework covered withcanvas. This section lies over the hole inthe floor through which the beam of x-rayscomes. The ionization chamber, seen closeto it, may be thrust through the small hole
