- anchoring the fiducial into the target region after the fiducial is inserted into the target region, the anchoring device opening as the fiducial has been inserted into the target region.
A fiducial apparatus, comprising:
- a body portion;
- and means for anchoring the body portion into the target region so that the fiducial apparatus cannot move, each anchoring device having an unanchored position and an anchored position, the unanchored position permitting the body portion to move within the target region and the anchored position anchoring the fiducial apparatus into the target region.
