An alternative to the Clarkson technique for calculating total scattered radiation is presented for use with 10 MV photon beams. When compared to the same field size and depth parameters, the resultant TMR values are in good agreement with results utilizing the Clarkson technique. Lengthy iterative procedures are avoided in this new scatter technique in favor of a more efficient SMR algorithm, thereby reducing the amount of required computation time. The speed and simplicity of this method make it especially amenable to use with small desk top computers and even programmable pocket calculators.
本文提出了一种用于10兆伏光子束的计算总散射辐射的方法，作为克拉克森技术的替代方法。与相同的射野尺寸和深度参数相比，所得的组织最大剂量比（TMR）值与使用克拉克森技术得到的结果高度吻合。这种新的散射技术避免了冗长的迭代过程，转而采用更高效的散射模型比（SMR）算法，从而减少了所需的计算时间。该方法的速度和简便性使其特别适合与小型台式计算机甚至可编程袖珍计算器配合使用。
