Table 4 Calculated RMS of precision of the points of the centerline positioning, separately for helix and torus models

From: Semi-automatic measurements and description of the geometry of vascular tree based on Bézier spline curves: application to cerebral arteries

Group N \(RMS_{mean}\) \(RMS_{median}\) \(RMS_{min}\) \(RMS_{max}\) \(RMS_{SD}\)
Helix 11 0.063 0.062 0.059 0.069 0.0034
Torus 25 0.061 0.062 0.041 0.076 0.0090
