Abstract

Claims (37)

1 . A system for generating a two dimensional (2D) roadmap image, comprising:

a processor circuit configured for communication with an ultrasound imaging device movable relative to a patient, wherein the processor circuit is configured to:

receive a first bi-plane or three dimensional (3D) image representative of a first volume within the patient and a second bi-plane or 3D image representative of a second volume within the patient;

register the first bi-plane or 3D image and the second bi-plane or 3D image to determine a first motion between the first bi-plane or 3D image and the second bi-plane or 3D image;

receive a third bi-plane or 3D image representative of a third volume within the patient;

register the third bi-plane or 3D image to at least one of the first bi-plane or 3D image or the second bi-plane or 3D image to determine a second motion between the third bi-plane or 3D image and the at least one of the first bi-plane or 3D image or the second bi-plane or 3D image;

generate a 2D roadmap image of a region of interest by combining the first, second, and third bi-plane or 3D images, based on the determined first motion and second motion; and

output, to a display in communication with the processor circuit, a screen display comprising the 2D roadmap image,

wherein two images of the first, second, and third bi-plane or 3D images are 3D images,

wherein one image of the first, second, and third bi-plane or 3D images is a bi-plane image, and wherein the processor circuit is further configured to:

register the two 3D images to each other;

register the bi-plane image to a nearest 3D image of the two 3D images;

extract image data from the bi-plane image; and

generate the 2D roadmap image based on the extracted image data.

2 . The system of claim 1 , wherein the processor circuit is configured to combine the first bi-plane or 3D image and the second bi-plane or 3D image by transforming the first bi-plane or 3D image relative to the second bi-plane or 3D image such that the first bi-plane or 3D image and the second bi-plane or 3D image are in a same coordinate system.

3 . The system of claim 1 , wherein the processor circuit is configured to:

identify an image landmark in each of the first bi-plane or 3D image and the second bi-plane or 3D image; and

combine the first bi-plane or 3D image and the second bi-plane or 3D image by transforming, based on the determined first motion, at least one of the first bi-plane or 3D image or the second bi-plane or 3D image such that the image landmark in the first bi-plane or 3D image is aligned with the image landmark in the second bi-plane or 3D image.

4 . The system of claim 1 , wherein the 3D images have lower resolution than the bi-plane images.

5 . A method for generating a two dimensional (2D) roadmap image, comprising:

receiving, at a processor circuit configured for communication with an ultrasound imaging device movable relative to a patient, a first bi-plane or three dimensional (3D) image of a first volume within the patient and a second bi-plane or 3D image of a second, overlapping volume within the patient;

registering the first bi-plane or 3D image and the second bi-plane or 3D image to determine a first motion between the first bi-plane or 3D image and the second bi-plane or 3D image;

receiving at a third bi-plane or 3D image representative of a third volume within the patient; registering the third bi-plane or 3d image to at least one of the first bi-plane or 3D image or the second bi-plane or 3D image to determine a second motion between the third bi-plane or 3D image and the at least one of the first bi-plane or 3D image or the second bi-plane or 3D image;

generating, with the processor circuit, a 2D roadmap image of a region of interest by combining the first, second, and third bi-plane or 3D images, based on the determined first motion and second motion; and

outputting, to a display in communication with the processor circuit, a screen display comprising the 2D roadmap image,

wherein two images of the first, second, and third bi-plane or 3D images are 3D images,

wherein one image of the first, second, and third bi-plane or 3D images is a bi-plane image, and

wherein the method further comprises:

registering the two 3D images to each other;

registering the bi-plane image to a nearest 3D image of the two 3D images;

extracting image data from the bi-plane image; and

generating the 2D roadmap image based on the extracted image data.

6 . The method of claim 5 , wherein generating the roadmap image includes transforming the first bi-plane or 3D image relative to the second bi-plane or 3D image such that the first bi-plane or 3D image and the second bi-plane or 3D image are in a same coordinate system.

7 . The method of claim 5 , wherein generating the roadmap image includes:

identifying an image landmark that is common to the first bi-plane or 3D image and the second bi-plane or 3D image; and

combining the first bi-plane or 3D image and the second bi-plane or 3D image by transforming, based on the determined first motion, at least one of the first bi-plane or 3D image or the second bi-plane or 3D image such that the image landmark in the first bi-plane or 3D image is aligned with the image landmark in the second bi-plane or 3D image.

8 . The method of claim 5 , wherein the bi-plane images have higher resolution than the 3D images.
