Table 1 Description of cases and irradiation techniques
From: GTV-based prescription in SBRT for lung lesions using advanced dose calculation algorithms
Case 1 | Case 2 | Case 3 | |
|---|---|---|---|
GTV | 1.0 cm3 | 3.6 cm3 | 32.8 cm3 |
PTV | 6.4 cm3 | 14.5 cm3 | 75.0 cm3 |
Novalis (Non-IMRT) | 10 coplanar and non opposed beams | 9 coplanar and non opposed beams | 10 coplanar and non opposed beams |
Cyberknife (circular collimators and flattening filter free) | 62 non coplanar beams | 58 non coplanar beams | 52 non coplanar beams |
Clinac (Non-IMRT) prescription like classical 3DRT with type A, extra-margin from PTV to field edge | 5 coplanar and non opposed beams | 7 coplanar and non opposed beams | 7 coplanar and non opposed beams |
