The organ limits are inviolable — a re-irradiation or a frail patient. Coverage is what you spend to stay under them.
Assume 60 Gy in 30 fractions of chemoradiotherapy to this lobe, 2 years ago — the cord reached 40 Gy and the oesophagus 55 Gy in that plan. The budgets below are what remains, stated by the case rather than computed from a registration.
Seeded from The Cancer Imaging Archive collection 4D-Lung, licensed CC BY 3.0. Prescription is a standard peripheral lung SABR regimen (54 Gy in 3 fractions, RTOG 0618 / AAPM TG-101 range) chosen for this challenge. It is not the treatment the patient received. Contoured structures: Trachea_c20, RLung_c20, LN_c20, LLung_c20, MarkerA_c20, MarkerB_c20, MarkerC_c20, Tumor_c20, Cord_c20, Esophagus_c20, Heart_c20, Carina_c20.
