With its safety and accuracy improvements the Model B X-Ray assured perfect results. It replaced earlier guesswork with an exact radiographic technique. The flexible and easy to adjust x-ray head contributed immensely toward the efficiency and simplicity of operations. Standardizing techniques and fixed factors insured uniform radiographs of correct details and density. Utilizing a new type of straight line focus tube and heavy-duty transformer, the greater output of x-ray energy available made possible not only intra and extra-oral examinations, but also enabled collaborative diagnosis with physicians pertaining to any bony structure of the body. Radiographs up to 14 x 17 inches were possible."
