Abstract

A computer-implemented medical visualization method includes identifying a three-dimensional model of an anatomical item of a particular mammal; displaying a moving animation of the three-dimensional model, the moving animation created from multiple frames from imaging of the anatomical item over a short time period to capture movement of the anatomical item; displaying one or more non-moving views of the three-dimensional model while the moving animation is being displayed; and in response to receiving inputs from a user, changing the displayed moving animation and the one or more non-moving views automatically in coordination with each other.

First claim

What is claimed is:

1. A computer-implemented medical visualization method, comprising:
identifying a three-dimensional model of an anatomical item of a particular mammal;
displaying a moving animation of the three-dimensional model of the anatomical item on a display, the moving animation of the three-dimensional model of the anatomical item created from multiple frames from imaging of the anatomical item over a short time period to capture movement of the anatomical item;
displaying one or more non-moving views of the three-dimensional model of the anatomical item on the display while the moving animation of the three-dimensional model of the anatomical item is being displayed;
displaying on the display, in coordination between the moving animation of the three-dimensional model of the anatomical item and the one or more non-moving views of the three-dimensional model of the anatomical item, an animation of a virtual medical device being moved through the three-dimensional model of the anatomical item; and
in response to receiving inputs from a user, changing the displayed moving animation of the three-dimensional model of the anatomical item and the one or more non-moving views of the three-dimensional model of the anatomical item automatically in coordination with each other.

2. The method of claim 1 , wherein the anatomical item comprises a heart.

3. The method of claim 1 , further comprising displaying forces applied on the anatomical item based on movement of the device through the anatomical item.

4. The method of claim 3 , wherein the displayed forces are determined by applying finite element analysis to a tissue model for the anatomical item.

5. The method of claim 1 , further comprising automatically determining whether the medical device makes contact with tissue in the anatomical item as the medical device is moved relative to the three-dimensional model of the anatomical item.

6. The method of claim 1 , further comprising performing computational fluid dynamics analysis for fluid flowing around the virtual medical device in the anatomical item, and displaying to the user information representing results of the computational fluid dynamics analysis.

7. The method of claim 1 , wherein the three-dimensional model of the anatomical item is generated by operations comprising:
obtaining data that represents imaged two-dimensional slices of the anatomical item captured by one or more medical imaging systems;
generating a three-dimensional intermediate representation from points identified in the two-dimensional slices; and
generating the three-dimensional model from the intermediate three-dimensional representation.

8. The method of claim 1 , wherein the moving animation is comprised of frames taken by imaging a real version of the anatomical item at different closely-related times, so as to show movement of the anatomical item.

9. The method of claim 1 , wherein a first non-moving view shows the anatomical item during a first imaging session, and a second non-moving view shows the anatomical item during a second imaging session.

10. The method of claim 9 , wherein the first imaging session is a pre-operative imaging session, and the second imaging session is a post-operative imaging session.
