The use of posterior wedge portals as an alternative to tissue compensators.
In a regional oncology center, where the patient census makes routine construction of tissue compensators prohibitive, a simple alternative can be successfully implemented. In this instance, a posterior wedge is used to alter isodose levels. This allows us to minimize critical structure doses, and optimize tumor dose levels. The following chest isodose distribution is presented for discussion.
