Texte intégralAdvances in the treatment techniques with ionizing radiation are resulting in complex dose distributions that need to be verified before the application of the treatment in the patient. Several dosimeters have been suggested for this application, but polymeric gel dosimeters are presenting the best results so far, since they allow three dimensional dose visualization, are tissue equivalent, don\'t have dependence with angular distribution of the incident radiation and have a high spatial resolution. In this work a polymeric gel dosimeter with national components, to reduce de costs and facilitate its introduction in the clinical practice was developed. Formaldehyde was added to the gel formulation to increase its melting temperature and facilitate its use in typical room temperatures found in our country. Dose response analysis was done using nuclear magnetic resonance relaxometry. All the dosimetric characterization was done. We found a linear dose-response curve for doses until 15Gy and significant energy dependence for low energy beams (kVp), but for high energy beams (MV) this dependence is smaller. The response variation when varying the dose rate of irradiation was smaller than 5% in the dose rate range of clinical use in teletherapy (100-600cGy/min). The addition of formaldehyde did not eliminate the dosimeter dependence with variation of the scanning temperature; the integrity of dose distribution was unaltered at least for a tree month period of time in a half beam irradiation phantom. Tri-dimensional dose distributions were measured in two radiotherapy systems using intensity modulated beams, the first one in a linear accelerator and the second in a tomotherapy machine. A high similarity was found between the overlapping of isodoses and dose profiles of the dose distribution measured with the gel and expected by the treatment planning. The real tri- dimensional analysis was done with dose-volume histograms (DVH) and the DVHs measured for the planning volume and expected by the treatment planning were in good agreement. Our results show that the modification done in the gel formulation resulted in a dosimeter easy to handle and feasible for tri-dimensional measurements.

Texte intégralThe International Commission on Radiation Units and Measurements (ICRU) recommends that the total radiotherapy treatment uncertainty should not exceeds 5%, in other words, considering that each step involved in the absorbed dose delivery process should not surpass the cited value (ICRU 50, 1993; ICRU 62, 1999). The uncertainties considered are those involved with, the machine installation (in this work, a Clinical Linear Accelerator), its acceptance, commissioning, followed by those related to subsequent quality controls and even new commissioning, if necessary. The minimum required physical dosimetric parameters to be commissioned for electron or photon beams are: the Percentage Depth Dose (PDD), the filtered and open Field Profiles, Total Scatter Factors (Scp), Cone Factor (Fcone), Transmission Factors: Wedge Filter (FF), Tray (FB), intra Leaf (FMLC,intra) and inter Leaf Leakage (FMLC,inter), besides the Virtual Source Position Determination (SSDeff). For this purpose, the American Association of Physicists in Medicine (AAPM), through its last protocol, provides guidelines on phantom and detector selections, setting up of phantom for data acquisition (for scanning and no-scanning data), procedures for acquiring the cited beam parameters with ionizing chambers (CI) and methods to reduce the total measurement error lower than 1% (AAPM TG 106, 2008). However, this protocol does not present any information or details about the physical dosimetric parameters for clinical linear accelerators (PFDALC), through gel dosimeters once they present several useful advantages for Radiotherapy, such as: soft tissue equivalence (Z and ), wide energy independence range for photons or electrons beams and high spatial resolution. The scope of this work is to present an innovative way for physical dosimetric parameters commissioning, specifically using the Fricke Xylenol Gel (FXG) dosimeter, like an alternative and/or complementary method to that employed internationally. Devices and procedures have been developed for this work in order to infer the cited parameters, in a practical, efficient and low cost way, compared to that used with CI (standard method). All the FXG results obtained were validated with the CI, considering the uncertainty recommended for the last one. The results suggest that the FXG effectively can be used for physical dosimetric parameters commissioning for clinical linear accelerators and a new specific protocol can be generated.

Texte intégralVolumetric Modulated Arc Therapy (VMAT) is one of the methods most commonly used in teletherapy to treat cancer. The various technological advances and the evolution of treatment techniques made the VMAT as one of the state of the art methods for the treatment of some cancers. Part of this improvement is credited to improvements in accuracy and prescription dose absorbed recommended to the patient over the years. This advance allows currently is possible to perform dosimetric calculations by means of the computerized planning system, considering the heterogeneity of patients, such as tissues and organs with different water compositions medium (reference radiation), and individual patient contour the movement of tumors breathing. Such advances require quality control of these tools, in order to ensure that the entire treatment process is satisfactory and accurate. Up to now, the community lacks an experimental system capable of evaluating, considering the uncertainty levels if the computerized planning systems are able to consider the movement of targets in the treatments with VMAT. In this paper, will be presented the results obtained with the phantom Fricke Xylenol Gel, capable of measuring the differences introduced by movement using the Magnetic Resonance Image - MRI and compared qualitatively and quantitatively. The main stages of the phantom development, their experimental results, conclusions and comparisons with other systems are discussed.

Texte intégralRadiotherapy is a procedure that uses high energy ionizing radiation directed to the tumor to destroy its cells. The objective is to obtain tumoral cells more damaged avoiding the healthy cells around it and increase this result. Due to the high complexity of the energy beams used on these treatments, a three-dimensional dosimeter is demanded to assure that the dose is focused as planned, being the polymeric gel dosimetry using Nuclear Magnetic Resonance Images (NMRI) for dose scanning an option to this measurement. This work uses MAGIC-f gel as reference and its objective is to optimize the dosimeter formulation, by initiallyreplacing the antioxidants agents (Copper Sulfate and Ascorbic Acid) by a more power rating antioxidant, Tetrakis (hydroxymethyl) phosphonium chloride (THPC), and then, variatingthe others dosimeter´s components concentration in order to obtain the smallest concentration of each one that result in an adequate dosimeter´ssensitivity for radiotherapy application. Studies were made to check the thermal stability of the gel containing THPC and studies were carried out about the ideals concentrations of THPC (2mM, 5mM, 8mM, 10mM or 20mM); Methacrylic Acid (2%, 2.5%, 3%, 3.5% or 4%); Gelatin (4%, 6%, 8% or 10%). After the modifications, the optimized formulation containing 88.96% of mili-Q water; 3% of methacrylic acid; 8% of gelatine; 0.04% of THPC (5mM) showed a sensitivity of approximately 1.03 Gy-1s-1 and a melting point approximately of 50°C, using the smallest possible chemical compounds concentrations and the NMRI scanning sequence implemented for this dosimetry. The optimized dosimeter obtained presents a 40% cost reduction, comparing with the dosimeter MAGIC-f, and a dose resolution of 0.18 Gy. The dosimeter responds linearlywith doses from 0 to 10 Gy. A maximal sensitivity variation of 8.5% was found when varing the dose rate from 300 to 500 cGy/min. Its dose integrity was checked by a half beam blocked irradiation. And its largestsensitivity variation at a repeatability test was 15%. The second objective of this work was the development of a methodology for reusing the dosimeter.The dosimeter previously irradiated with 2Gy was reused after being melted in a digitaltemperature control oven at 50°C, followed by the re-addition of THPC and a new gelation. The reused MAGAT gel dosimeter with 1mM of THPC presented 30% sensitivity reductioin when compared to the the same dosimeter before the reusing process, while the MAGAT gel with 2mMof THPC presented a reduction of only 15%

Texte intégralThe 3D monomeric gel dosimetry is an important tool in radiation therapy cases which needs high spatial dose resolution. In this work we developed a methacrilic acid monomeric gel called MAGIC® to evaluate spatial dose distributions in simulations of radiation therapy treatments. We used two Magnetic Resonance Imaging (MRI) techniques, the relaxometry (RT) and the magnetization transfer (MT). The work was developed in three stages. First of all, the phantoms were created to be irradiated using and x radiations, the MRI were acquired and analyzed. We also developed a software, programmed in Matlab®, to analyze the images and to draw isodoses curves of irradiated phantoms. Following it, we improved the way the gel was prepared and its composition, as well the image acquisition and processing. In this part we added formaldehyde to the gel, improving its sensibility in 15%. Finally, we simulated 5 different radiation therapy treatments and compared the isodoses measured with the isodoses of the radiation therapy treatment planning software (TPS®). The results of the RT technique corresponded to our expectations. Using the RT we characterized the gel with dosimetric tests and evaluated five different radiation therapy treatments. The gel showed a linear relation with the dose until 20 Gy, but the results of the tests were not reproducibles, because of that we made a calibration curve for each test. The effective atomic number of the gel is close to the water, so it was not necessary any correction. In most of the simulated cases, the isodoses measured with the gel reproduced the virtual simulations. Unfortunately, until now, we didn\' t have the same success using the MT technique. The MT images were not reliable and because of that the simulations were only made with the RT technique.

Texte intégralIn this work the main dosimetric characteristics of the Fricke Xylenol Gel (FXG) solution were established for further application in the measurement of dose distribution of clinical electron fields. The dose-response curves of the FXG in a neutron field were also evaluated for the research in Boron Neutron Capture Therapy (BNCT) and industrial electron fields. The standard reading technique was the spectrophotometric. For the clinical field, the intra and inter-batch reproducibility are better than 1.4% and 5.1 %, respectively, the response presents a linear behavior for doses ranging from 0.2 to 40 Gy independently of the energy and the dose rate in the studied ranges. Due to the effects of the FXG natural oxidation, the optimum elapsed time between FXG preparation and irradiation was established as 24h period and the behavior of the dose-response curve of the FXG using the variation in the absorbance relative to the non-irradiated dosimeter as a basis during the whole studied period were not altered. The dose-response to the industrial electron beam presented an exponential decreasing behavior and the neutron beam for research in BNCT presented a linear behavior for the complete studied dose range. According to the obtained results for the different types of radiation studied for the FXG, there was no change in the position of the characteristic bands of the absorption spectrum due to the interaction of these radiation types. Additional tests were performed to determine the digital photographic imaging of FXG analyses viability and the application of FXG dosimetry on intracavitary brachytherapy. The good performance of the FXG dosimeter in the tests that were carried out indicates that this dosimeter may be applied to the tri-dimensional dose evaluation in radiotherapic treatments using electrons and neutron beams.

Texte intégralResearchs with radiation dosimeters look for materials that presents similar response to radiation as biological systems. This work presents preliminar characterization and radiotherapy application from a new chemical dosimeter (FXGA), derived from the FXG with a difference due to the gelatin used (pork skin \"300 Bloom\" for FXG and national gelatin for FXGA). The FXGA absorbed dose reading are based on the optic absorption, and for this reason a reader (RADIARE III) was developed, which is portable and economically accessible when compared with an spectrophotometer. From the measurements done, it can be inferred that FXGA dosimeter possess linear response with the absorbed dose from 0.5 up to 35 Gy for 60Co photons and from up 1 up to 7 Gy for 5, 8 and 10 MeV. The energy dependence for photons and electrons were obtained and their response are coherent those expected. FXGA radiotherapy applications had been done as field factor, profile and percentage depth dose for 60Co photons. From the characterization results for photons and electrons, as well from physical parameters for the 60Co , one can figure out that the dosimetric system \"FXGA gel + RADIARE III reader\" can be an attractive tool for the quality control in a radiotherapy service.

Texte intégralRadioterapy uses ionizing radiation to destroy tumor cells. The absorbed dose control in a target volume is done through dosimetry, using radiation sensors, being the Fricke and film used in this study. Among several types of cancer indicated for treatment using ionizing radiation, there is also the Mycosis Fungoides (MF), lymphom that spreads on surface and depth in the skin, for which high-energy electrons are used for its treatment. In this work the Fricke Xylenol Gel (FXG) was used for MF treatment control, to obtain the absorbed dose distribution from electrons interaction with the tissues. For this scope cuvettes were manufactured of acrylic (slices), with the same contours of the skull and abdomen anthropomorphic simulator tomos. Once filled with the FXG, these cuvettes were used to infer the absorbed dose by the anthropomorphic simulator Rando Phantom. This simulator, completed with the cuvettes and radiochromic films, this last one also with the same contours similar to skull and abdomen were submitted to the Stanford technique, for 6 MeV electrons total body irradiation. CCD and radiographic density images were acquired and evaluated by horizontal and vertical profiles through theirs centers. These profiles were analyzed through a computer programs: one developed in Matlab for FXG images and the other by an already known program, ImageJ, for film images. From the results one can infer that the FXG dosimeter presents similarity with that of film, in the evaluation of the absorbed dose distribution on surface and also inside of the patient.
