Fig. 6From: Optimization of training periods for the estimation model of three-dimensional target positions using an external respiratory surrogateChanges in 3D RMSEs due to differences in the correction period for the modeling period of (a) four-dimensional cone-beam computed tomography, (b) 5 s, (c) 10 s, (d) 15 s, (e) 25 s, (f) 35 s, and (g) 70 s. White triangles: outliers out of range. Black triangles: outliers observed in patient included apnea and hyperpnea dataBack to article page
