RT Journal T1 POsitioning in radiography JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1939 FD August 26 VO 113 IS 9 SP 882 OP 882 DO 10.1001/jama.1939.02800340152035 UL http://dx.doi.org/10.1001/jama.1939.02800340152035 AB This is the most elaborate book on roentgenographic technic ever published. The paper is excellent. The presswork is impeccable. The illustrations are balanced between photographs and drawings of an instructive character and an adequate number of roentgenograms showing the results which appear in the roentgenographic film. An extraordinary amount of preparatory work was undertaken to produce this master guide to roentgenographic technic. The price is not excessive, considering the magnificence of the illustrations, the carefully worded descriptive text and the accurately detailed instruction as to the exposure factors. It is hardly possible to speak in terms of too much praise for this beautiful volume.
