Field border separations for adjacent orthogonal fields can be calculated geometrically, given the validity of some important assumptions such as beam alignment and field uniformity. Thermoluminescent dosimetry (TLD) measurements were used to investigate dose uniformity across field junctions as a function of field separation and, in particular, to review the CCSG recommendation for the treatment of medulloblastoma with separate head and spine fields.
在一些重要假设（如射束对准和射野均匀性）有效的情况下，相邻正交射野的射野边界间距可以通过几何方法计算。热释光剂量测定法（TLD）测量用于研究射野交界处的剂量均匀性与射野间距的函数关系，特别是回顾儿童癌症研究组（CCSG）关于髓母细胞瘤采用分开的头部和脊髓野进行治疗的建议。
