Object used to align or calibrate a vision system; it can provide a stable reference for colour, brightness, size, unique identification, or position relative to some unknown being measured.
The IMRT boost was delivered with daily online correction of fiducialmarker position.
2
The prostate set-up errors that would result from skin marker set-up, off-line bony anatomy-based protocols and online fiducialmarker-based corrections were determined.
3
After the fiducialmarker is recognized, the virtual image is superimposed onto the real environment, forming the "integrated image" on semi-transparent glass.
4
Conclusions: The gold fiducialmarkers demonstrated negligible effect on DWI quality.
5
Therefore, gating without implanted fiducialmarkers is a promising clinical direction.

2
Digital fluoroscopy was used to measure respiratory-induced motion of implantedfiducial markers within the prostate.
3
The margin required for set-up errors was found to be 10-15 mm unless implantedfiducial markers are available for treatment guidance.
