System and method of graphically generating anatomical structures using ultrasound echo information

A medical system for use with an anatomical structure, comprising:

• an elongated medical probe including a shaft having a distal end and a signal emitting element carried by the shaft distal end;
• at least one processor configured for:
• generating data, based on signals emitted by the element, while the distal probe end is moved within the anatomical structure;
• defining a plurality of three-dimensional geometric shapes, based on the generated data, within a coordinate system;
• and
• graphically generating a representation of at least a portion of the anatomical structure based on the geometric shapes.

A method of graphically creating a representation of an anatomical structure, comprising:

• moving the distal end of an elongated probe within the anatomical structure;
• defining geometric shapes within a coordinate system while the distal probe end is moved within the anatomical structure, each of the geometric shapes originating from the distal probe end;
• determining a union of the geometric shapes;
• and
• graphically generating a representation of at least a portion of the anatomical structure based on the union of the geometric shapes.
