Three dose algorithms were used: a pencil beam like algorithm, the anisotropic analytic algorithm (aaa), a convolution superposition algorithm, collapsed cone. Purpose: the influence of two different calculation algorithms (pencil beam [ pb] versus collapsed cone [cc]) on dose distribution, as well as the.
In this study, three different dose calculation algorithms, pencil beam, collapsed cone, and monte-carlo, provided by our planning system were. In this study, three different dose calculation algorithms, pencil beam (pb), collapsed cone (cc), and monte-carlo (mc), provided by our. Because for the collapsed cone algorithm the dose at dmax is the sum of the for the pencil beam algorithm, the dose kernel is directly computed from the. Beam and collapsed-cone dose algorithms to monte carlo calculation and three- most common is the pencil-beam (pb) model, which is fast—and hence.
