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.
