OTION radiography, a subject of 

 intense intere t, both to the pro- 

 f essiona 1 



world and to the lai- 

 ty, has been unsuc- 

 cessfully attempted 

 for the past eight 

 years. Scientists, 

 with the aid of the 

 fluoroscope, have 

 been able to see the 

 inner working of the 

 human body. The 

 fluoroscope is a fluo- 

 rescent screen hav- 

 ing a hood for the 

 protection of the 

 physician's eyes. 

 With this instru- 

 ment it is possible 



Using X-rays to locate a fracture of the 

 forearm. The rays can penetrate a wall 



to see the shadows 



cast by objects in the path of the 

 X-ray. 



Dr. E. L. Crusius of New 

 York city, after months of 

 experimenting has accom- 

 plished motion radiography 

 to the extent of showing the 

 joints in motion. He is now 

 experimenting to show the pul- 

 sations of the heart, the pe- 

 culiar wave-like motion of the 

 stomach in digestion, the ex- 

 pansion of the lungs in breath- 

 ing and other organic motions 

 in the human body. 



Dr. Crusius hopes to be able 

 to give his findings to the 

 Government within a short 

 time. Now that the X-ray 

 has entered the motion picture 

 world, the general j)ublic will 

 be able to see how great an 

 assistance the X-ray can be lo 

 the physician. This is es-

pecially true in surgical work in the army 

 for tracing bullets and locating fractures. 

 As an example of the benefit to be de- 

 rived from an X-ray examination, take 

 the case of a fiacture which is very 

 common. This, fracture is generally 



caused by dropping a heavy object on the 

 foot. The injured person usually binds 

 up the foot after rubbing on some lini- 

 ment. That one f the delicate bones 

 may be broken 

 never occurs to him. 

 The result of this is 

 that the bone grows 

 together in an ab- 

 normal position, so 

 that all the rest of 

 his life the owner of 

 the foot experiences 

 difficulty in walk- 

 ing. An X-ray 

 would have revealed 

 the fracture, the 

 bone could have 

 been set in the 

 proper position and 

 in a short time the 

 patient would have been as well as ever. 

 The X-ray machine used by Dr. Crusius 

 in his work generates five hun- 

 dred thousand volts. The rays 

 are exceedingly powerful, in 

 fact they can penetrate a six- 

 foot stone wall. 



The exploration of one's 

 anatomy by the X-ray is ac- 

 complished without any more 

 pain or unpleasant after effects 

 than would be experienced in 

 having a photographer take an 

 ordinary, look-pleasant-please 

 photograph. As the X-ray is 

 a straight ray and cannot be 

 turned or deflected in any 

 way, the great difficulty in 

 making motion radiographs 

 has been to get a screen placed 

 between the X-ray and the 

 camera that would not fog the 

 film and at the same time 

 would show the image. Dr. 

 Crusius has accomplished this.
