An 5 estimated surface of the organ is computed based on the measurements. A three-dimensional (3D) shell of the organ, which extends inwards from the estimated surface of the organ and has a predefined thickness, is defined. A quality of the anatomical mapping is estimated based on 10 the measurements whose locations fall within the 3D shell.1/4 Nt Nt 0) 00 C14 co co CV) d ft ULft C14 C'14 A A ) cn N cn Q) N C14 04 co 04 C14 C14 ON 00 C14 cn cn CO cn
