[Dosimetry of a whole-body irradiation for bone marrow transplantation].
The authors present a method allowing to dose a whole-body irradiation in such a way that a nearly homogenous dose of 10 Gy is reached in the whole patient, with the exception of the lung which shall only receive 8 Gy. Particular attention is given to the increased dose in the head and neck region caused by the smaller thickness as compared to the trunk, which is compensated by shields. The measurements were taken in a plastic phantom for all possible patient's dimensions. All necessary basic data are stored in a program which calculates the monitor preselection for the individual fields after input of the patient's dimensions. Further controls are intended in the near future by in-vivo measurements. The time necessary for the described measurements is about for to six days, and the same time has to be appended for the evaluation and establishment of the program.
