Abstract
A method for fusing two digitized image datasets for 2-dimensional visualization of the heart, includes providing a first digitized image and a second digitized image, each image acquired from a different imaging modality and each comprising a plurality of intensities corresponding to a domain of points on a 3-dimensional grid, and wherein the first and second images have been registered, segmenting the heart in one of said digitized images, forming a 2-dimensional maximum intensity projection of a surface of said heart from each of said digitized images, and fusing said images by overlaying one 2-dimensional projection of said surface over the other 2-dimensional projection of said surface.

A method of fusing two digitized image datasets for 2-dimensional visualization of the heart, comprising the steps of:
- providing a first digitized image and a second digitized image, each image acquired from a different imaging modality and each comprising a plurality of intensities corresponding to a domain of points on a 3-dimensional grid, and wherein the first and second images have been registered;
- segmenting the heart in one of said digitized images;
- forming a 2-dimensional maximum intensity projection of a surface of said heart from each of said digitized images;
- and
- fusing said images by overlaying one 2-dimensional projection of said surface over the other 2-dimensional projection of said surface.
A method of fusing two digitized image datasets for 2-dimensional visualization of the heart, comprising the steps of:
- providing a digitized computed tomography (CT) image and a digitized positron emission tomography (PET) image, each image comprising a plurality of intensities corresponding to a domain of points on a 3-dimensional grid;
- segmenting the heart surface in said CT image;
- modeling the heart surface with a 3-dimensional ellipsoid and forming a 2-dimensional projection of said heart surface from each of said digitized images;
- and
- overlaying a 2-dimensional projection from said CT image over a 2-dimensional projection from said PET image.
A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform the method steps for fusing two digitized image datasets for 2-dimensional visualization of the heart, comprising the steps of:
- providing a first digitized image and a second digitized image, each image acquired from a different imaging modality and each comprising a plurality of intensities corresponding to a domain of points on a 3-dimensional grid, and wherein the first and second images have been registered;
- segmenting the heart in one of said digitized images;
- forming a 2-dimensional maximum intensity projection of a surface of said heart from each of said digitized images;
- and
- fusing said images by overlaying one 2-dimensional projection of said surface over the other 2-dimensional projection of said surface.
The computer readable program storage device of claim 16, wherein one of said images is acquired from a positron emission tomography (PET) scan, and the other of said two images is acquired from a computed tomography (CT) scan.
