为了研究Brahme提出的适形治疗的不变核形式，提出了一种治疗计划方法。通过将旋转对称、不变核与加权分布进行卷积来计算三维剂量分布。在阵列处理器上实现的傅立叶变换卷积技术用于实现高计算速度，从而允许在空间和频域中的迭代技术用于计算渐进地接近所需剂量分布的剂量分布。为了使用旋转对称核，解决方案的一般性被用于快速、确定性、逆规划方法。这种损失的一般性所施加的剂量分布的限制的特点和初步的结论得出这种形式的方法的临床应用的潜力和限制。提出了这一概念的进一步发展。
A treatment planning methodology was developed to investigate the invariant kernel form of conformal therapy proposed by Brahme. Three‐dimensional dose distributions were calculated by convolving a rotationally symmetric, invariant kernel with weighting distributions. Fourier transform convolution techniques implemented on an array processor were used to achieve high calculation speeds, thereby allowing iterative techniques in the spatial and frequency domains for computing dose distributions that asymptotically approach a desired dose distribution. To use rotationally symmetric kernels, the generality of the solution is traded for a fast, deterministic, inverse planning approach. The limitations imposed on the dose distributions by this loss of generality are characterized and tentative conclusions are drawn about the potentials and limits of clinical application of this form of the methodology. Further developments of the concept are suggested.
