Figure 1. Target volumes of a patient treated with CT-based SBRT.

Figure 1

Fusion of simCT (a) and MRI (b) are seen. Navy blue: PTV (33 Gy/5 fractions); red: ITV (40 Gy/5 fractions, SIB); dark green: body; light green: liver; brown: bowel; pink: left kidney; blue: right kidney; yellow: spinal cord.

CT = computed tomography; SBRT = stereotactic body radiation therapy; simCT = simulation computed tomography; MRI = magnetic resonance imaging; PTV = planning target volume; ITV = internal target volume; SIB = simultaneous integrated boost
