IMRT, however, requires the placement of fiducial markers to guide treatment delivery. Fiducials are particularly important in patients after radical prostatectomy because of the lack of a definitive target. Challenges also exist in clearly delineating the prostate bed because of postsurgical anatomical ...
includes the steps of: with respect to the work piece, defining a path having a radius from an origin which varies in a non-repetitive manner with respect to the angular displacement of the path from the origin; and selecting two or more prospective locations of respective fiducial markers. ...
The needle manipulator 300 includes a plurality of fiducial markers 10a, 10b, 10c and 10d in the first rotary guide 1 and fiducial markers 10e, 10f, 10g through 10h (10e not shown) on the second rotary guide 3, as described in the first embodiment. In addition, at least the first ...
Fiducial marker placement was confirmed in the intended location of the prostate or prostate bed for 297 of 300 markers (99%) on follow-up CT imaging. Two markers were placed just outside the prostate capsule, and one marker was lost. Complications included sepsis (n = 1; 1.3%), self-...

Tracking of moving tumors currently requires the use of implanted radiographic markers (or fiducials) as reference points [1, 7]. Several reports describe the placement of fiducials through surgical or percutaneous methods under image guidance (ultrasonography or computed tomography) in the prostate, ...
