Gold Markers...New tech for better cancer treatment

Different types of gold markers

Today's high-precision radiotherapy technologies for prostate cancer treatment require accurate localization of the gland just prior to and during radiation delivery. The implantable fiducial markers paired with localization software allow to position the target accurately and spare surrounding tissue.

Gold Soft Tissue Markers are pure gold cylinders specially knurled to inhibit migration. Standard Gold Soft Tissue Markers are 3mm long and 0.8, 0.9, 1.2 or 1.6mm in diameter. They are available as loose markers or in sterilized preloaded needles for ease of use. 

The use of Implanted Fiducial Gold Markers is now standard procedure for external beam radiotherapy treatment of the prostate. Treatment margins can be reduced with image-based verification and correction for the prostate position. This ensures precision targeted radiation and reduces the dose to surrounding normal tissues (e.g. rectal wall, bladder).

Gold markers are clearly visible on CT and MR scans and can be used for CT-MR fusion for improved delineation of the prostatic gland.
