However, many variations exist in the TBI procedure, such as the irradiation technique, total dose, dose rate and dose fractionation. In TBI treatment, it is important to apply a homogeneous dose to the total body, and avoid interstitial pneumonitis and cataracta. Therefore, we applied a four-field technique using 10 MV X-rays with a shield for lungs and eyeballs, and employed tissue compensators and bolus to obtain a homogeneous dose distribution. The midpoint doses in 12 positions of the total body have been achieved within±10% of that of the pelvis with the use of this technique. Also, this TBI technique is capable of accurately controlling absorbed doses to the lungs and eyes. http://ci.nii.ac.jp/naid/110003471555 公益社団法人日本放射線技術学会 1993-12-01 jpn journal article VoR http://hdl.handle.net/2298/19798 https://kumadai.repo.nii.ac.jp/records/24830 03694305 日本放射線技術學會雜誌 49 12 1999 2006 https://kumadai.repo.nii.ac.jp/record/24830/files/110003471555.pdf application/pdf 1.1 MB 2020-03-02
