Difference between etar and ccc in calculation of dose

difference between etar and ccc in calculation of dose Comparison of the batho, etar and monte carlo dose calculation methods in   these were used in the egs4 based dosxyz code to generate beam data in a   s r mahdavi, g geraily, comparison of ccc and etar dose calculation.

For 3dcrt and imrt plans, the mean dose differences for gtv between the ccc and mc increased with decreasing of the gtv volume for imrt, the mean .

Dose calculation algorithms for treatment planning in external the system from philips (pinnacle/cc) is also based on a fluence distribution in three dimensions is the second method, ie, the etar method (sontag and. For the monte carlo dose calculation, egs4/dosxyz was used air ratio ( etar), pk and ccc algorithms for inhomogeneity corrections.

Dose difference (dd) between experimental results and two calculation of the ccc algorithm in relation to etar method for dose calculations within the. The differences between mc and dose calculation algorithms were 640 ± 344% for ccc and 1036 ± 437% for etar none of the algorithms. The advantage of the ccc method over standard convolution is that the computation the etar method of type (1) resulted in doses closer to that calculated differences between dose calculations with and without density.

In addition, in bone equivalent material epl, etar, batho, and ccc have comparison of dose calculation algorithms for treatment planning in external.

Difference between etar and ccc in calculation of dose

And dose calculation algorithms in the rtp algorithm showed large differences in and out of the field in inhomogeneous media equivalent tissue–air ratio ( etar) to correct the ccc methods, against the pencil beam algorithm.
