Review of Fricke gel dosimeters
The innovation of adding a gel matrix to the traditional Fricke dosimeter to stabilize geometric information established the field of gel dosimetry for radiation therapy. A discussion of Fricke gels provides an overview of the issues that determine the dose response of all gel dosimeters in general. In this paper we review some of the features of Fricke systems to illustrate these issues and, i...
متن کاملFricke dosimetry for synchrotron stereotactic radiotherapy
In synchrotron stereotactic radiotherapy (SSR) the tumor is loaded with a high Z element, and exposed to monochromatic x-rays from a synchrotron source, in stereotactic conditions. The SSR treatment efficiency is related to the heavy element concentration achievable in the tumor, to the radiation energy, and the irradiation geometry [1,2]. The experimental dose verification of SSR in three dime...
متن کاملمروری بر انواع دزیمترهای سه بعدی
Modern radiotherapy techniques try to deliver the radiation dose by steep gradient. Protocols for these complex treatment delivery techniques are important and extremely sensitive to errors in treatment delivery. To minimize such errors, 3D dosimeters were developed as a relative method for improving dose monitoring and delivery. The aim of this study is to analyze the capability and drawbacks ...
متن کاملDosimetry in HDR brachytherapy with Fricke-gel layers and Fricke-gel catheters
Fricke-gel layer dosimeters (FGLD) and Fricke gel dosimetric catheters (FGDC) have been designed and tested with the aim of enquiring their suitability for HDR Ir brachytherapy source control and for in-vivo dose verification during treatment. Anisotropy function measurements have been carried out with FGLDs in which a thin plastic tube has been placed in for the Ir source insertion. FGDCs are ...
متن کاملStereotactic radiosurgery photon field profile dosimetry using conventional dosimeters and polymer gel dosimetry. Analysis and inter-comparison
Small photon fields are increasingly used in modern radiotherapy and especially in IMRT and SRS/SRT treatments. Accurate beam profile measurements of such beams are crucial for a precise and effective treatment. In this work four different dosimetric methods have been used for profile measurements of three small 6 MV circular fields having diameters of 7.5, 15.0 and 30.0 mm. A small sensitive v...
