“…To minimize these effects, various types of detectors with small sensitive volumes (e.g. diodes and diamond) have been developed and characterized [1]. The aim of this study is to evaluate the characteristics of the dosimetric system developed by Nuclear Energy Department of UFPE (DEN) for small-field photon beam dosimetry under conditions of SRS.…”

The stereotactic radiosurgery (SRS) is a technique that uses multiple beams extremely collimated of ionizingradiation to treat intracranial lesions and functional abnormalities, with high geometric precision and dosimetricaccuracy. The use of small fields is already a reality in modern radiotherapy techniques. However, the accuracyin small-field dosimetry is challenging because of several process physics and aspects related to the detector. Theaim of this paper is to evaluate the response of a dosimetric system developed by Nuclear Energy Department ofFederal University of Pernambuco (DEN/UFPE) for small field dosimetry. Measurements of, output factor (OF),off-axis ratio (OAR) and percentage depth dose (PDP) were performed with this dosimetric system andcompared with the results obtained with a commercial diode and treatment planning system data. The resultsshowed that the Diode-DEN presents a reliable and economical alternative for small fields dosimetry used intreatments of SRS. This detector can be used for validation of dates obtained in commissioning of linearaccelerator and inserted in Treatment Planning Systems (TPS).
