RADIOBIOLOGIC AND DOSIMETRIC PROBLEMS IN RADIOTHERAPY OF BRAIN TUMORS. AN EXPERIMENTAL AND CLINICAL STUDY
Thesis/Dissertation

OSTI ID:4840971
Studies were made on dosimetry in roentgen irradiation of brain tumors, radiobiologic studies on tolerance of brain tissue in rabbits and man, and radiosensitivity of brain tumors. Several conclusions are given: After correction for bone absorption in the absorption of radiation in human brain tissue, standard tables could be used for dose calculation in the treatment of brain tumors. In the study of dose distribution in treated areas, it was found that appreciable improvement can be attended only by radical modification of the technique. The assumption that time-dose relationship curves for brain and skin in any given mammal will correspond seems justified. Discussion is also given on the reliability of depth dose tables, time-dose relationship curves for brain and skin reactions in rabbits, and the comparison between slope and dose range in rabbits and man.
