Abstract
Abstract In a system and a method for generating an image that contains superimposed or fused image data, a first system acquires an image dataset from a subject and a second system obtains a video image of the subject. The positions of the first, the second systems in the acquisition of the image datasets are determined with the an arrangement for position determination, such as a navigation system, with reference to which the position of the image dataset acquired with the first system and the position of the video image dataset can be determined in space, so that the two image datasets can be superimposed or fused with one another. An arrangement also can be provided for generating a video image expanded with image data of the image dataset acquired with the first system.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
117 words
A system for generating an image, comprising: a first system for acquiring an image dataset from a subject; a second system for obtaining a video image of the subject; a unit for generating first position information comprising a position of the first system during acquisition of said image dataset and a position of the second system while obtaining said video image; a unit for obtaining second position information comprising a position of the image dataset and a position of the video image; and a computer for combining said image data and said video image in a combining operation selected from the group consisting of super-imposition and fusion, using said first position information and said second position information.
Claim 2
Independent Claim
117 words
A system for generating an image, comprising: a first system for acquiring an image dataset from a subject; a second system for obtaining a video image of the subject; a unit for generating first position information comprising a position of the first system during acquisition of said image dataset and a position of the second system while obtaining said video image; a unit for obtaining second position information comprising a position of the image dataset and a position of the video image; and a computer for combining said image data and said video image in a combining operation selected from the group consisting of super-imposition and fusion, using said first position information and said second position information.
Claim 3
Dependent Claim
34 words
A system as claimed in claim 1 wherein said unit for generating first position information also identifies a position of the subject and includes said position of the subject in said first position information.
Claim 4
Dependent Claim
19 words
A system as claimed in claim 1 wherein said unit for generating first position information is a navigation system.
Claim 5
Dependent Claim
20 words
A system as claimed in claim 1 wherein said first system acquires a 3-D image dataset as said image dataset.
Claim 6
Dependent Claim
15 words
A system as claimed in claim 1 wherein said first system is an x-ray system.
Claim 7
Dependent Claim
15 words
A system as claimed in claim 1 wherein said first system is an ultrasound system.
Claim 8
Dependent Claim
25 words
A system as claimed in claim 1 wherein said second system is selected from the group consisting of an endoscope, a laparoscope, and a catheter.
Claim 9
Dependent Claim
55 words
A system as claimed in claim 1 wherein said first system acquires a medical image dataset as said image dataset and wherein said second system obtains a video image of an internal region of the subject, and wherein said computer combines said medical image dataset and said video image to produce a medical diagnostic image.
Claim 10
Independent Claim
127 words
A method for generating an image, comprising the steps of: acquiring an image dataset of a subject with a first system; obtaining a video image of the subject with a second system; generating first position information comprising a position of said first system during acquisition of said image dataset and a position of the second system while said video image is obtained; generating second position information comprising a position of the image dataset and a position of the video image; combining data in said image dataset and data in said video image in a combining operation selected from the group consisting of super-imposition and fusion, using said first position information and said second position information, to produce combined data; and generating an image from said combined data.
Claim 11
Independent Claim
127 words
A method for generating an image, comprising the steps of: acquiring an image dataset of a subject with a first system; obtaining a video image of the subject with a second system; generating first position information comprising a position of said first system during acquisition of said image dataset and a position of the second system while said video image is obtained; generating second position information comprising a position of the image dataset and a position of the video image; combining data in said image dataset and data in said video image in a combining operation selected from the group consisting of super-imposition and fusion, using said first position information and said second position information, to produce combined data; and generating an image from said combined data.
