Planning aims at the Royal Marsden and Rigshospitalet for high-dose TBI. Dmin is minimum dose, Dmax maximum dose.
| Planning aims | Rigshospitalet | The Royal Marsden |
|---|---|---|
| Prescribed dose for high-dose TBI | 12 Gy (2 Gy × 6) | 14.4 Gy (1.8 Gy × 8) |
| Lungs | V_100% < 2% | V_100% < 2% |
| Lungs | V_10.2 Gy > 95% | |
| Lungs | Mean dose as low as possible – it usually end up around 93% (11.3 Gy) | Mean lung dose between 12 and 12.5 Gy, lower preferred Usually 85% (12.24 Gy) |
| Brain | V_12 Gy < 5% | Dmin > 13 Gy (90%) Dmean ∼ prescription dose Dmax < 15.8 Gy (110%) |
| Kidneys | Should receive between 10.2 and 12 Gy | D5% < prescription dose Mean kidney dose between 12 and 12.5 Gy, lower preferred |
| PTV (the body excluding the outer 5 mm of body and excluding the lungs) | Dmin > 90% (10.8 Gy) | |
| PTV (the body excluding the outer 5 mm of body and excluding the lungs) | Dmax < 110% (13.2 Gy) | |
| Body | Dmin > 80% | Dmin > 80% |
| Body | The volume receiving more than 120% should be as small as possible | No part of the patient should receive > 17.3 Gy (120%) |
