Helen Cassell was fluoroscoped by the new Chamberlain Multiplane Fluoroscopic Unit at Good Samaritan hospital in June 1949. X-ray technician Alice Grinnell was operating the machine. The unit, which cost the hospital $10,000, was to be of great value in examination of orthopedic an bronchoscopy patients. The fluoroscope was used to observe shadows cast by objects in the path of X-rays. They had been in use for some time but this new machine, unlike earlier models that were mounted on the floor, was mounted on ball bearings in the ceiling and could rotate around a patient. At the time, even the Mayo Clinic did not have one. Herald-Leader Archive Photo
