Abstract
Abstract An image display system is provided with an image display apparatus (1) for displaying an image, the image being dependent on the position and orientation of the image display apparatus and independent of the position and posture of a user of the image display apparatus. An image guided surgery system is provided with such an image display system in order to show the user, during a medical treatment utilizing an instrument, where within the patient the instrument is situated, without the user having a direct view of said instrument.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
114 words
An image display system comprising: an image display apparatus for displaying a derived image of an object, the image display apparatus being positioned adjacent to the object and being moveable with respect to the object, and an image processing unit for processing previously-recorded image information of the object into the derived image, wherein the derived image corresponds to an instantaneous position and/or orientation of the image display apparatus relative to the object but is independent of the instantaneous position and orientation of a head of a user viewing the image display apparatus, whereby the user can move to view the adjacent object without the derived image displayed on the image display apparatus being changed.
Claim 2
Dependent Claim
114 words
An image display system comprising: an image display apparatus for displaying a derived image of an object, the image display apparatus being positioned adjacent to the object and being moveable with respect to the object, and an image processing unit for processing previously-recorded image information of the object into the derived image, wherein the derived image corresponds to an instantaneous position and/or orientation of the image display apparatus relative to the object but is independent of the instantaneous position and orientation of a head of a user viewing the image display apparatus, whereby the user can move to view the adjacent object without the derived image displayed on the image display apparatus being changed.
Claim 3
Dependent Claim
30 words
An image display system as claimed in claim 1, further comprising a position detection system for measuring a position and/or orientation of the image display apparatus relative to the object.
Claim 4
Dependent Claim
34 words
An image display system as claimed in claim 2, wherein the image display apparatus includes a transmission device for transmitting a position signal which represents the position and/or orientation of the image display apparatus.
Claim 5
Dependent Claim
20 words
An image display system as claimed in claim 1, wherein the image display apparatus includes a liquid crystal display screen.
Claim 6
Dependent Claim
16 words
The system of claim 1 wherein the previously-recorded image information concerns the interior of the object.
Claim 7
Dependent Claim
23 words
The system of claim 1 wherein the image display apparatus further comprises controls for adjusting or selecting the display of the derived image.
Claim 8
Dependent Claim
152 words
An image-guided surgery system comprising: an image display apparatus for displaying a derived image of an patient, the image display apparatus being positioned adjacent to the patient and being moveable with respect to the patient, a position measuring system for measuring a position of an instrument and a position of the moveable image display apparatus, and an image processing unit for processing previously-recorded image information of the patient into the derived image, wherein the derived image represents the measured position of the instrument in an operating zone of the patient and corresponds to the measured position and/or orientation of the image display apparatus relative to the patient but is independent of the position and orientation of a head of a user viewing the image display apparatus, whereby the user can move to view the operating zone of the adjacent patient without the derived image displayed on the image display apparatus being changed.
Claim 9
Dependent Claim
152 words
An image-guided surgery system comprising: an image display apparatus for displaying a derived image of an patient, the image display apparatus being positioned adjacent to the patient and being moveable with respect to the patient, a position measuring system for measuring a position of an instrument and a position of the moveable image display apparatus, and an image processing unit for processing previously-recorded image information of the patient into the derived image, wherein the derived image represents the measured position of the instrument in an operating zone of the patient and corresponds to the measured position and/or orientation of the image display apparatus relative to the patient but is independent of the position and orientation of a head of a user viewing the image display apparatus, whereby the user can move to view the operating zone of the adjacent patient without the derived image displayed on the image display apparatus being changed.
Claim 10
Dependent Claim
21 words
An image-guided surgery system as claimed in claim 7, wherein the image display apparatus includes a holder for supporting the instrument.
Claim 11
Dependent Claim
20 words
An image display system as claimed in claim 2, wherein the image display apparatus includes a liquid crystal display screen.
Claim 12
Dependent Claim
20 words
An image display system as claimed in claim 3, wherein the image display apparatus includes a liquid crystal display screen.
Claim 13
Dependent Claim
27 words
An image display system as claimed in claim 7, which also includes a position detection system for measuring a position and/or orientation of the image display apparatus.
Claim 14
Dependent Claim
34 words
An image display system as claimed in claim 7, wherein the image display apparatus includes a transmission device for transmitting a position signal which represents the position and/or orientation of the image display apparatus.
Claim 15
Dependent Claim
