| Abstract: |
A system and method for producing three-dimensional representations of an object. A first series of projected images of the selected object is recorded in a first projection plane and a second series of projected images of the selected object is recorded in a second projection plane. The first and the second series of projected images are rendered at a common magnification. The first set of projected images is then integrated into a first three-dimensional volume and the second set of projected images is integrated into a second three-dimensional volume. The three-dimensional representation of the object is then produced by combining one projected image from the first set of projected images with one projected image from the second set of projected images. Alternatively, the three-dimensional representation is produced by merging the first three-dimensional volume with the second three-dimensional volume.

First Claim:

What is claimed is:
1. A system for synthesizing a three-dimensional representation of a selected object from a plurality of projected radiographic images of the selected object comprising:
- a. at least one radiographic recorder for recording radiographic images of the selected object;
- b. at least one source of radiation for irradiating the selected object to enable projected radiographic images of the selected object to be recorded on the radiographic recorder;
- c. an image synthesizer for synthesizing a three-dimensional representation of the selected object from selected projections of the projected radiographic images recorded on the radiographic recorder; and
- d. a display for displaying the three-dimensional representation, the display comprising:
- i. stereoscopic spectacles to be worn by an observer;
- ii. a target operatively connected to the stereoscopic spectacles;
- iii. a detector operatively associated with the target for tracking movement of the target; and
- iv. a monitor connected to the detector for receiving a signal from the detector indicative of movement of the target and for displaying an image pair of the three-dimensional representation in response to the signal.
