The influence to present depth doses and peripheral doses by enhanced dynamic wedge and physical wedge

Purpose: To understand the influence to depth doses and peripheral doses by Enhanced Dynamic Wedge and physical wedge.Methods: The depth doses and peripheral doses were measurement for open field and Enhanced Dynamic Wedge field as well as physical wedge.Results: (1) depth doses and peripheral doses for Enhanced Dynamic Wedge fields was very similar to those for open fields; (2) depth doses and peripheral doses for physical wedge fields was large than those for open fields. Conclusion: depth doses measured for open fields can also be used for Enhanced Dynamic Wedge fields dose calculation. Wedge depth dose must be used in the physical wedge fields dose calculation. It should be pay attend to peripheral doses for physical wedge fields in the clinic.
