Fig. 3From: ITV versus mid-ventilation for treatment planning in lung SBRT: a comparison of target coverage and PTV adequacy by using in-treatment 4D cone beam CTa Target coverage per treatment for the different PTV margins. Target coverage per treatment is plotted in (b) as a function of the tumor motion amplitude vector. On boxplots (a), the cross represents the 10th percentile and highlights the minimum target coverage obtained for at least 90% of the patientsBack to article page
