  • Title: [The radiobiological aspects in the blocking of sensitive structures from the irradiation field].
    Author: Dubben HH, Herrmann T.
    Journal: Strahlenther Onkol; 1995 Apr; 171(4):214-7; discussion 218. PubMed ID: 7740409.
    Abstract:
    BACKGROUND: In some cases the total dose has to be reduced in a section of an irradiation field by means of a transmission block. This can be performed in 2 different ways: 1. A part of the planned fractions is blocked. 2. The dose of each fraction is reduced using a transmission block (transmission < 100%). METHOD: For both methods the biological tumor and normal tissue doses were calculated using the linear-quadratic model. A clinical case is discussed. RESULT AND CONCLUSION: With transmission blocks a therapeutic gain can be obtained.
