RT Journal A1 Kirsh IE T1 IS a fluoroscope useful to the general practitioner? JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1959 FD July 4 VO 170 IS 10 SP 1141 OP 1142 DO 10.1001/jama.1959.03010100003002 UL http://dx.doi.org/10.1001/jama.1959.03010100003002 AB Recent concern over the amount of ionizing radiation to which the public is exposed raises the question of the safety and utility of the fluoroscope in the general practitioner's office. There is evidence that the amount of exposure during fluoroscopy varies widely, as does the output of the fluoroscopes actually found in use. The busy practitioner does not always take time for his eyes to achieve maximal dark adaptation, and optimal filtration and other safety precautions have often been neglected. Fluroscopy is most valuable in observing abnormal movements. It therefore supplements the data obtained from roentgenography, which is otherwise more precise, yields permanent records, and gives more diagnostic information in proportion to the amount of radiation involved.
