Abstract

Abstract Image data is acquired and a spatial coordinate system is attached to the image data set. A navigational guide employs the attached coordinate system to indicate to the viewer the orientation of the imaged object and the location of the viewer with respect to the imaged object. This indication is made in a number of ways, including the display of an icon which depicts the orientation of the object being viewed.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 90 words
In an imaging system for viewing a three-dimensional image data set acquired with a medical imaging system, the method comprising: attaching a spatial coordinate system to the acquired three-dimensional image data set which indicates a reference orientation and location of an object being imaged; displaying an image of the object that is reconstructed from data in the acquired three-dimensional image date set; and displaying a navigational guide which employs the attached spatial coordinate system to indicate the position or orientation of the viewer with respect to the object being displayed.
Claim 2
Dependent Claim 90 words
In an imaging system for viewing a three-dimensional image data set acquired with a medical imaging system, the method comprising: attaching a spatial coordinate system to the acquired three-dimensional image data set which indicates a reference orientation and location of an object being imaged; displaying an image of the object that is reconstructed from data in the acquired three-dimensional image date set; and displaying a navigational guide which employs the attached spatial coordinate system to indicate the position or orientation of the viewer with respect to the object being displayed.
Claim 3
Dependent Claim 25 words
The method as recited in claim 1 in which the navigational guide is an icon which is a pictorial representation of the object being imaged.
Claim 4
Dependent Claim 23 words
The method as recited in claim 1 in which the navigational guide is an icon which is a pictorial representation of a human.
Claim 5
Dependent Claim 72 words
The method as recited in claim 1 which includes: inputting viewer orientation data which indicates a change in viewer orientation with respect to the spatial coordinate system; changing the orientation of the view of the object being displayed to correspond with the viewer orientation data; and transforming the displayed navigational guide by a corresponding amount to indicate the new position or orientation of the viewer with respect to the object being displayed.
Claim 6
Dependent Claim 31 words
The method as recited in claim 1 in which the spatial coordinate system is manually attached to the acquired image data set by inputting data which defines two orthogonal spatial coordinates.
Claim 7
Dependent Claim 31 words
The method as recited in claim 1 in which the spatial coordinate system is manually attached to the acquired image data set by inputting data which defines three orthogonal spatial coordinates.
Claim 8
Dependent Claim 100 words
In a system for displaying a stored three-dimensional image of an object, the method comprising: attaching a spatial coordinate system to the stored three-dimensional image; inputting from a viewer data which indicates the orientation of the viewer with respect to the stored three-dimensional image of the object; displaying the stored three-dimensional image at an orientation indicated by the data input from the viewer; displaying an icon representative of the object being imaged; and orienting the icon on the display using the attached spatial coordinate system to indicate to the viewer the direction from which the displayed object is being viewed.
Claim 9
Dependent Claim 100 words
In a system for displaying a stored three-dimensional image of an object, the method comprising: attaching a spatial coordinate system to the stored three-dimensional image; inputting from a viewer data which indicates the orientation of the viewer with respect to the stored three-dimensional image of the object; displaying the stored three-dimensional image at an orientation indicated by the data input from the viewer; displaying an icon representative of the object being imaged; and orienting the icon on the display using the attached spatial coordinate system to indicate to the viewer the direction from which the displayed object is being viewed.
Claim 10
Dependent Claim 39 words
The method as recited in claim 7 in which the viewer may input further data to change the orientation at which the stored image is being viewed and the icon is reoriented on the display by a corresponding amount.
Claim 11
Dependent Claim 19 words
The method as recited in claim 8 in which the icon is a pictorial representation of the imaged object.
Claim 12
Dependent Claim 29 words
The method as recited in claim 7 in which the spatial coordinate system is manually attached to the stored image by inputting data which defines two orthogonal spatial coordinates.
Claim 13
Dependent Claim 29 words
The method as recited in claim 7 in which the spatial coordinate system is manually attached to the stored image by inputting data which defines three orthogonal spatial coordinates.
Claim 14
Dependent Claim 117 words
An imaging system for viewing a three-dimensional image data set acquired with a medical imaging system, which comprises: means for attaching a coordinate system to the acquired three-dimensional image data set which indicates a reference orientation and location of an object being imaged; means for selecting a viewing location and viewing orientation within the three-dimensional image data set; means for displaying an image of the object at the viewing location and viewing orientation that is constructed from data in the acquired three-dimensional image data set; and means for displaying a navigational guide which employs the attached spatial coordinate system to indicate the viewing position or viewing orientation of the viewer with respect to the object being displayed.
Claim 15
Dependent Claim 117 words
An imaging system for viewing a three-dimensional image data set acquired with a medical imaging system, which comprises: means for attaching a coordinate system to the acquired three-dimensional image data set which indicates a reference orientation and location of an object being imaged; means for selecting a viewing location and viewing orientation within the three-dimensional image data set; means for displaying an image of the object at the viewing location and viewing orientation that is constructed from data in the acquired three-dimensional image data set; and means for displaying a navigational guide which employs the attached spatial coordinate system to indicate the viewing position or viewing orientation of the viewer with respect to the object being displayed.
Claim 16
Dependent Claim 26 words
The imaging system as recited in claim 12 in which the navigational guide is an icon which is a pictorial representation of the object being imaged.
Claim 17
Dependent Claim 37 words
The imaging system as recited in claim 13 in which the means for displaying a navigational guide rotates the icon with respect to the attached spatial coordinate system in response to changes in the selected viewing orientation.
Claim 18
Dependent Claim 20 words
The imaging system as recited in claim 14 in which the cion is a three-dimensional representation of a human body.
Claim 19
Dependent Claim 42 words
The imaging system as recited in claim 13 in which the means for displaying a navigational guide indicates a location on the icon that moves with respect to the attached spatial coordinate system in response to changes in the selected viewing location.
