Margins needed to be applied for patients with high risk prostate cancer when matching on fiducial markers (FM), soft tissue (ST), bones (B) or balloon (ERB)
| M (mm) CBCT | ST (mm) CBCT | B (mm) CBCT | Ba (mm) CBCT | M (mm) kV | B (mm) kV | Ba (mm) kV | |
|---|---|---|---|---|---|---|---|
| Anterior | 10.52 | 10.94 | 12.28 | 11.99 | 10.88 | 12.18 | 11.62 |
| Posterior | 6.39 | 6.94 | 8.85 | 8.44 | 6.94 | 8.68 | 7.99 |
| Long | 9.67 | 9.72 | 11.23 | 10.71 | 10.19 | 11.24 | 14.23 |
| Lat | 7.39 | 7.76 | 7.80 | 7.95 | 7.53 | 7.88 | 9.11 |
For low risk prostate cancer patients the prostate only was treated. For high risk prostate cancer patients the prostate and the seminal vesicles were treated.
