Influence of shields missing tissue and inhomogeneities
(abridged)
. .
,
,
Presently, only simple correction algorithms are applied in some TPS. The
effect of these algorithms must be verified and documented.
yes
Published shielding or tissue inhomogeneity data are based on MC.
Validation of these MC data should be done by comparing with measured

data, such as those obtained using TLD or small ionisation chambers.

Algorithms are under development to account for scatter conditions and
tissue inhomogeneities.

Validation of these algorithms should be done in a similar way to the method
