Radiotherapeutic physics. I. The physical aspects of treatment of cancer by 22 MeV X-rays.

Recently a number of papers dealing with the use of betatron radiation in cancer therapy have been published by workers at the University of Illinois (Adams et al., 1948; Chase, Quastler, and Skaggs, 1947; Koch, Kerst, and Morrison, 1943; Luce, Quastler, and Skaggs, 1949; Quastler, 1945; Quastler and Clark, 1945; Quastler, et al. 1949; Quastler and Lanzl, L. H., 1950; Skaggs, Almy, Kerst, and Lanzl, L. H., 1950; Skaggs, Almy, Kerst, and Lanzl, L. H. 1948), in the General Electric (Charlton and Breed, 1948), at the University of Saskatchewan (Johns, Darby, Haslam, Katz, Harrington, 1949; Johns, Darby, Watson, Burkell, 1950), and in Great Britain (Fry, 1949; Mayneord, Martin, and Layne, 1949). The Illinois group have reported in detail (Quastler et al., 1949) on the first cancer treatment with the betatron. Since March 1949 the betatron in the Physics Department of the University of Saskatchewan has been used by Dr. T. A. Watson and Dr. C. C. Burkell of the Saskatchewan Cancer Commission in the treatment of...
