Anatomical modeling from a 3-d image and surface mapping

Abstract

The invention relates to an anatomical modeling from a 3-D image and a surface mapping. A method of medical imaging includes creating an anatomical map of an inner wall of a cavity in a body of a subject by inserting a probe into the body and collecting data using the probe. A three dimensional (3-D) contour is delineated in a 3-D image of the cavity based on the map.

Description

technical field [0001] The present invention relates generally to medical imaging systems, and in particular to methods and systems for constructing three-dimensional views of internal organs. Background technique [0002] Three-dimensional (3-D) images of internal organs are useful in many catheter-based diagnostic and therapeutic applications, and real-time imaging is widely used during surgical procedures. Ultrasound imaging is a relatively convenient real-time imaging modality, however the resolution of real-time ultrasound imaging is generally not as good as that obtained from other imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). [0003] US Patent 6,106,466 to Sheehan et al., the disclosure of which is incorporated herein by reference, describes a method for generating a 3-D model of the heart from 2-D ultrasound images. Anatomical locations are manually identified in the 2-D images. A 3-D mesh was used as the prototype heart...
