Abstract
The effects of random (drifting) errors in actual seed placement during prostate implants have been evaluated by using geometrically optimized implants of I-125 and Pd-103 seeds. Results indicate that small random deviations in the seeds placement from the preplant position may affect the planned dose and beam profiles significantly.
