McIntosh et al. IJROBP 71:603-610. 2008
- 2-, 3-, 4-, 5- and 7-field beam arrangements with fixed coplanar beams
- comparison with non-coplanar 3D-CRT and IMRT plans for one patient
- coplanar partial breast
topotherapy
provides good target coverage with
exceptionally
low dose to organs at risk
- use of
more than five fields
provided
no additional dosimetric advantage
- a comparison of five-field topotherapy to 3D-CRT and IMRT illustrates equivalent target
conformality and uniformity
