From: Biological impact of geometric uncertainties: what margin is needed for intra-hepatic tumors?
The effects of motion plus random error and motion plus systematic error. The percentage dose errors are shown for patients with motion amplitudes greater than 1 cm and less than 1 cm. Data are shown for different margin recipes resulting in different CTVs (CTV, CTVa, and CTVb) and over a variety of different radiosensitivities (SF2 = 0.7, 0.5 and 0.3). The effects of motion plus random error and motion plus systemic error are separated in the two graphs. The error bars indicate 1 standard deviation.
