An Analysis on the Prostate Deformation during Brachytherapy Needle Insertion

Abstract

In this paper is presented a theoretical study and analysis regarding the usage of finite elements on deformations of human internal organs (prostate) that emerge at the claim for puncture by brachytherapy needles. Therefore, in medical practice has been observed that at the insertion of thick needles, some of the internal organs are deformed long enough until the moment in which the external tissues are breached. This deformation of the organs can be an important source of error for special procedures, such as those necessary to perform a brachytherapy, causing an uneven distribution of radioactive seeds into the affected organ. Thereat, the present study aims to determine the dependencies between certain factors related to the insertion procedure of brachytherapy needles and the value of the deformation of the organs.
