Mean tracking errors in LR, SI, and AP compared with the mean standard-of-care errors for all 13 cases investigated. The standard deviations of the errors were plotted as error bars. Cases marked with asterisks indicate that markerless tumor tracking resulted in significantly smaller errors than the standard of care. LR: left-right; SI: superior-inferior; AP: anterior-posterior.
