insertion of intraprostate gold fiducial markers in prostate cancer treatment

A low cost vision based localization system using fiducial markers ?

This paper investigates a mobile robot self-localization system based on fiducial markers which are placed on the ceiling. Recently there have been many articles related to path planning and coordination of mobile agents within an unknown environment. These algorithms demand dedicated (and often expensive) hardware that is capable of handling complex tasks in real time. In this paper, we have e...

Prostate MRS in the presence of gold seed fiducial markers

MR Spectroscopy (MRS) has great potential for guiding radiotherapy of prostate cancer by identifying bulky and/or high grade tumors suitable for dose escalation (1,2). However, image guided therapy typically employs permanently implanted gold seed fiducial markers (GSFM), which aid in daily prostate localization prior to treatment. The impact of these gold seed markers on the quality of MRS is ...

Daily online localization using implanted fiducial markers and its impact on planning target volume for carcinoma prostate.

BACKGROUND Aim of the study was to assess prostate motion on daily basis with respect to setup and to compare the shifts based on bony anatomy and gold fiducial markers. MATERIALS AND METHODS Gold fiducial markers were inserted in prostate under U/S guidance and daily portal images were taken and compared with digitally reconstructed images, both using bony landmarks and fiducial markers as r...
