A comparative study of surface dose and dose distribution for intact breast following irradiation with field-in-field technique vs. the use of conventional wedges.
Dose to the contalateral breast is a traditional concern with the use of wedges in breast irradiation. A solution is to treat using field-in-field technique (segmental dose), which also provides a more uniform dose distribution to the irradiated volume. In this experiment, an anatomical phantom was scanned, planned, and treated using 3 different treatment techniques. Thermoluminescent dosimetry was used for verification and to measure skin surface dose on both breasts.
