Abstract
A method includes calculating a medial-axis tree graph of a volume of an organ of a patient in a computerized anatomical map of the volume. A predefined number of major branches in the tree graph are identified. Using the identified major branches, one or more known anatomical opening regions of the volume are identified in the anatomical map.

A method for automatic identification and processing of anatomical structure in an anatomical map, comprising:
- calculating a medial-axis tree graph of a volume of an organ of a patient in a computerized anatomical map of the volume;
- identifying a predefined number of major branches in the tree graph;
- and
- using the identified major branches, identifying in the anatomical map one or more known anatomical opening regions of the volume.
A system for automatic identification and processing of anatomical structure in an anatomical map, comprising:
- a memory configured to hold a computerized anatomical map of a volume of an organ of a patient;
- and
- a processor, which is configured to:
- calculate a medial-axis tree graph of the anatomical map;
- identify a predefined number of major branches in the tree graph;
- and
- using the identified major branches, identify in the anatomical map one or more known anatomical opening regions of the volume.
