External radiotherapy is one of the most common treatments for prostate cancer. Conformal Radiation Therapy (CRT) is a specific subset of radiation therapy aimed at preserving normal tissue, while controlling the tumour locally. There are uncertainties associated with radiotherapy: setup variations, patient motion and organ motion. In order for CRT to be affective, the prostate position must be known at treatment time, for proper dose delivery. Electronic Portal Imaging Devices (EPIDs) make use of the radiation beam to obtain portal images. These images help determine tumour position. To visualize the prostate on plain X-ray, three gold seeds are implanted into the prostate. In this thesis, a simple and fast automatic seed detection algorithm is presented, permitting the localization and tracking of the prostate during treatment. The tests indicate that in all cases considered the seeds are properly detected in portal images without any human intervention.
