Method and system for producing interactive, three-dimensional renderings of selected body organs having hollow lumens to enable simulated movement through the lumen
First Claim
1. A medical system for interactively displaying three dimensional structures from a three-dimensional volume of data representing at least one physical property associated with a three dimensional body, comprising:
- a) a data isolator configured to isolate a selected region of interest from the volume of data based on selected values of the physical property representing the isolated region of interest, wherein the data isolator comprises a thresholder configured to determine threshold values corresponding to the selected the physical property to isolate the selected region of interest; and
b) an image renderer configured to render the isolated region of interest in an interactive three-dimensional display, wherein the thresholder comprises a threshold range selector configured to select a threshold range corresponding to the selected values of the physical property representing the region of interest and a threshold adjustor configured to adjust threshold values to establish the threshold range for isolating the region of interest.

Abstract
A method and system are provided for effecting interactive, three-dimensional renderings of selected body organs for purposes of medical observation and diagnosis. A series of CT images of the selected body organs are acquired. The series of CT images is stacked to form a three-dimensional volume file. To facilitate interactive three-dimensional rendering, the three-dimensional volume file may be subjected to an optional dataset reduction procedure to reduce pixel resolution and/or to divide the three-dimensional volume file into selected subvolumes. From a selected volume or subvolume, the image of a selected body organ is segmented or isolated. A wireframe model of the segmented organ image is then generated to enable interactive, three-dimensional rendering of the selected organ.
