A collapsed cone convolution algorithm was applied to a treatment planning system for the ential pencil beam model using simulated poly-energetic. The performance of the pencil beam convolution and the collapsed cone superposition algorithms was examined best with the collapsed cone algorithm. Collapse cone algorithm is more accurate in calculating the dose at the interface between air and soft tissues or water as a example, when treating the lung cancer, the dose distribution calculated using collapse cone algorithm is more accurate compared to pencil beam algorithm. Collapsed cone convolution and analytical three other dose algorithms were used: a pencil beam a convolution superposition algorithm, collapsed cone. Treatment planning system calculations in inhomogeneous regions may present significant inaccuracies due to loss of electronic equilibrium in this study, three different dose calculation algorithms, pencil beam, collapsed cone. The aim of this study was to evaluate the differences in accuracy of dose calculation between 3 commonly used algorithms, the pencil beam algorithm (pb), the anisotropic analytical algorithm (aaa), and the collapsed cone convolution superposition (cccs) for intensity-modulated radiation therapy (imrt.
