Abstract
The present invention relates to a method and apparatus for reducing metal artifact in image reconstruction. In at least one embodiment, the method for reducing metal artifacts in image reconstruction comprises collecting at least one uncalibrated image (an X-ray or fluoroscopic image for example) and calibrating the at least one uncalibrated image, forming at least one calibrated fluoroscopic image. A patient to transmitter transform is computed using at least the at least one calibrated image. A reconstructed volume is formed using at least a patient to transmitter transform. At least two of the at least one calibrated fluoroscopic image, the patient to transmitter transform and the reconstructed volume may be combined, forming at least one display image. This image may then be displayed, using a display device for example.
