Abstract

An imaging system comprising an image capture apparatus, arranged to capture a stereoscopic image of an operator work site, in communication with a display system; the display system arranged to receive and display said stereoscopic image on a display screen to said operator; wherein said display system is arranged such that the display screen is placed intermediate the operator's eyes and the work site.

First claim

The invention claimed is:

1. An imaging system for capturing a stereoscopic image of a surgery work site and displaying the stereoscopic image to a surgery operator, the imaging system comprising:
an image capture apparatus, arranged to capture a stereoscopic image of a microsurgical work site, in communication with a display system;
the display system arranged to receive and display said stereoscopic image on a display screen to said operator;
wherein the display screen is supported by a selectively movable frame so as to be capable of selectively moving the display screen into and out of alignment of the operator's eyes and the microsurgical work site;
wherein said image capture apparatus includes a pair of cameras, the difference in images captured by said cameras consistent with the difference in images captured by the unassisted eyes of the operator;
wherein said image capture apparatus further includes mirrors corresponding to each camera, the mirrors being arranged to direct the respective images to said corresponding cameras along paths substantially parallel to the display screen and so display the stereoscopic image at an angle the same as that of the operator's unassisted eyes so as to provide stereoscopic depth perception for the spatial relationship of elements with the microsurgical work site.

2. The system according to claim 1 , wherein said movable frame comprises a resiliently deformable arm mounted between said frame and an anchor point, said arm capable of deforming to a range of positions subject to the requirements of the operator.

3. The system according to claim 1 , further including shutter glasses, wearable by the operator to provide alternating images shown on the display screen to the operator.

4. The system according to claim 1 , wherein the display screen displays the images directed in differing directions so as to permit each image to correspond with the relevant eye.

5. The system according to claim 1 , wherein said mirrors are curved.

6. The system according to claim 1 , wherein the display system includes two display screens so as to permit two operators working simultaneously within the work site to view the stereoscopic image.

7. The system according to claim 1 , wherein the display screen alternates four images corresponding to two pairs of images so as to permit two operators working simultaneously within the work site to view the stereoscopic image.

8. The system according to claim 1 , wherein said cameras and said mirrors are located below said display screen and between said display screen and the work site.

9. The system according to claim 1 , wherein said stereoscopic image of the work site is displayed on said display screen at substantially the same location and orientation as would be seen of the work site with the unassisted eyes of the operator.

10. The system according to claim 8 , wherein said cameras each have an axis aligned horizontally with respect to the display screen.
