Systems and methods for constructing images
First Claim
Patent Images
1. A method of constructing a voxel-based representation of an anatomical structure, the method comprising the steps of:
- (a) acquiring a plurality of images of the anatomical structure;
(b) defining a space of voxels, each having a size, with respect to the acquired images;
(c) determining distances between the acquired images;
(d) based on the determined distances and the voxel size, creating a sufficient number of interpolated images between the acquired images such that a sufficent number of voxels between images are intersected by pixels from at least one acquired image or interpolated image; and
(e) assigning values to the voxels based on the intersecting pixels.

Abstract
Techniques and systems for constructing a three-dimensional representations of anatomical structures from a series of images of the structure include creating interpolated images between actual images and defining voxels based on pixel values of the actual and interpolated images. A three-dimensional representation of the structure may be constructed based on the voxels.

11. A method of constructing a three-dimensional representation of an anatomical structure from a series of images, the method comprising:
-
(a) defining a reference coordinate system about the anatomical structure; (b) determining a plurality of intersection lines between a first plane substantially orthogonal to a first axis of the reference coordinate system and an image from the series of images; (c) for each intersection line, defining an array having a number of positions based on a length of the intersection line; (d) placing pixel values from each position of each intersection line into respective positions in the corresponding arrays; (e) repeating steps (b) through (d) for additional planes along the first axis; and (f) constructing a three-dimensional representation of the anatomical structure based on the pixel values stored in the arrays. - View Dependent Claims (12, 13)

14. A system for constructing a voxel-based representation of an anatomical structure, the system comprising:
-
(a) a register for storing a plurality of images of the anatomical structure; (b) a processor configured to (i) define a space of voxels, each having a size, with respect to the anatomical structure, (ii) determine a distance between the images, (iii) based on the determined distances and the voxel size, create a sufficient number of interpolated images between the stored images such that a sufficient number of voxels between the images are intersected by pixels from at least one image or interpolated image, and (iv) assign values to the voxels based on the intersecting pixels; and (c) a display for displaying a three-dimensional representation of the anatomical structure constructed from voxels. - View Dependent Claims (15, 16, 17, 18, 19, 20)
