RECOMMENDATIONS - STANDARD PARAMETERS OF TBI

  1. As a general rule, the distance, patient position, beam quality and all treatment conditions are imposed by the facilities of every centre.
  2. The best sterility conditions are preferred for the treatment room, the material used and all the staff involved.
  3. Sufficient uniformity of dose cannot be achieved by using bilateral incidence alone, therefore, AP-PA incidence is recommended to achieve the best homogeneity of dose distribution and to shield the lung optimally.
  4. The beam quality index should be reported in order to compare dosimetric data from different institutions.
  5. To guarantee the reproducibility of geometrical data and the alignment of shielding and dosimeters, it is recommended that some verification methods should be used before or during the treatment.

Dosimetric measurements performed in antropomorphic phantoms are desirable.
