Abstract

In view the good clinical results obtained and the technological advancement, several innovations have been incorporated to brachytherapy treatment technique, for example, 3D planning systems and computer-guided sources. In detriment to scientific advances there are no protocols that relate dose with tumor volume, organs or the A point, established by ICRU38 and used to prescribe dose in treatment planning system. Several international studies have been trying to correlate the dose volume using 3D planning systems and medical images, as those obtained by CT or MRI. In order to establish an international cooperation between two research centers this project involves a one year stage at Maastro Clinic in the Netherlands, an active research center, which have been publishing several studies related to brachytherapy of which the student intends to participate actively, as well as developing a large part of his doctoral plan, enjoying the researchers experience and the structure available in the institution.
