Abstract
A method includes receiving an anatomical mapping that includes multiple measurements acquired at multiple respective locations within an organ of a patient. An 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 the measurements whose locations fall within the 3D shell.
Claims12
A method, comprising:
- receiving an anatomical mapping, comprising multiple measurements acquired at multiple respective locations within an organ of a patient, the multiple measurements including a physiological property of the organ acquired by an electrode at the multiple respective locations, and 3-D coordinates of the multiple respective locations;
- computing an estimated surface of the organ based on the measurements;
- defining a three-dimensional (3D) shell of the organ, which extends inwards from the estimated surface of the organ and has a predefined thickness;
- and
- estimating a quality of the anatomical mapping, based on the measurements whose locations fall within the 3D shell.

Apparatus, comprising:
- an interface;
- and
- a processor, configured
- to receive from the interface an anatomical mapping, comprising multiple measurements acquired at multiple respective locations within an organ of a patient, the multiple measurements including a physiological property of the organ acquired by an electrode at the multiple respective locations, and 3-D coordinates of the multiple respective locations,
- to compute an estimated surface of the organ based on the measurements, to define a three-dimensional (3D) shell of the organ, which extends inwards from the estimated surface of the organ and has a predefined thickness, and
