Method and system of generating a 3D visualization from 2D images

摘要

The invention relates to the field of computerized generation of a visualization from a plurality of images. In particular, the invention relates to generating a three-dimensional (3D) visualization from a plurality of two-dimensional (2D) medical images. The images may be obtained from an ultrasound device. Regions of interest are segmented in at least two images and the region of interest is then tracked and segmented among the remaining images.

1. A method for generating a three dimensional visualization from a plurality of two dimensional images obtained by a transverse scan, the method comprising the steps of:
generating a plurality of transverse scans of a target area with an image generation device; segmenting a region of interest in each image by:
projecting a plurality of radial profiles at angularly equi-spaced radii from a lumen centroid to an edge of the lumen, wherein end points of the plurality of radial profiles form a closed contour;modeling the lumen using a multi-level thresholding algorithm to identify a plurality of pixels of the image which are within the region of interest;obtaining an ellipse to encapsulate the region of interest; andtemporally smoothing the region of interest in each image; tracking an anatomical structure within the region of interest between each image; and rendering a three-dimensional visualization using said segmented and tracked region of interest.
