Full textThe use of Monte Carlo simulation in radiology has been growing with the appearance of different simulation codes that have been developed specifically for applications in radiology, as for example PENELOPE. Each of these codes use different algorithms for particle transport resulting in different levels of difficulty for its use as well as of accuracy and performance. The PENELOPE code uses a mixed algorithm for radiation transport that is defined by entrance parameters. Most of the applications of PENELOPE code have been performed with high energy beams, however the influence of the entrance parameters in the particle transport is not established for applications evolving radiodiagnostic beams and thin geometries. Specifically for the study of dosimetric characteristics of radiation detectors that have small thicknesses, as ionization chambers, the algorithm transport influences the results of the simulation. In this work, the study of the influence of entrance parameters on the transport algorithm used in PENELOPE Monte Carlo simulation code was performed by the simulation of the linear attenuation coefficients in different materials, thickness and energies used in radiodiagnostic. The validation of this code in such energy range allowed the determination of the backscatter factor for polienergetic beams, aiding its application in radiodianogsis.

Full textThe use of Monte Carlo simulation to the radiation transport in matter has been widly applied in the radiological and dosimetric areas. In Nuclear Medicine it is possible to use a variety of simulation codes as tools to study different response characteristics of dose calibrators used to measure radionuclides activities. The PENELOPE (Penetration and ENErgy LOss of Positron and Electrons) Monte Carlo simulation code has a mixed algorithm for the transport of radiation, which condenses the interaction events according to the input parameters. In this work, the PENELOPE code of simulation was used to study the response of an ionization chamber as function of parameters influencing its response. The chamber efficiency was tested by simulation and it showed a good agreement with calculated results. To the activity, its response showed a linear behavior for all studied nuclides, allowing one to obtain its sensitivity by simulation and measurements. The response of the chamber as a function of the energy obtained by simulation also showed a good agreement with the measurements, allowing one to extrapolate it to energies below and above the measured ones. The analysis with the volume of radiopharmaceuticals and position of the sourse in the chamber well obtained by simulation showed the expected behavior compared to the ones in literature. PENELOPE was validated to study this ionization chamber, so allow one to perform geometric and material parameters studies without experimental costs and difficulties.

Full textElectron beam radiotherapy has been used frequently for treatments of superficial tumors, due its characteristics of well-defined range and high dose gradient at low depth. For new radiotherapy techniques with this type of beam, a strict quality control is necessary for a safe implementation. Protocols recommend that the quality control for electron beams must be performed with an ionization chamber. However, thermoluminescent dosimeters, films and diodes are also used for this purpose. Although, these dosimeters do not have a set of essential characteristics for performing quality control, like high spatial resolution, low energy dependence, possibility of use in high dose gradients and three dimensional dose distribution acquisition. The present work evaluated the use of MAGIC-f gel dosimeter for the quality control in radiotherapy with electron beams. The readings of the gel samples were made by magnetic resonance imaging and Monte Carlo simulation was used to compare the obtained results. As part of a quality control for the electron beam parameters as percentage depth dose and beam profile were determined. Also beam quality factors, such as R50, were calculated in reference conditions and for small fields. The obtained results were compared with clinical data and MAGIC-f the maximum obtained difference was 4%. In addition, dose distributions from clinical applications with electron beams were evaluated by the gamma index. Considering the criteria of 3% DD and 3 mm DTA, the results showed concordance greater than 94% for all dosimetric methods. Thus, according to the dosimetric measurements through MAGIC-f gel dosimeter it can be inferred that the gel dosimeter can be used as auxiliary tool in the quality control procedures in radiotherapy to electron beam. Also, MAGIC-f is a useful a tool to determine tridimensional dose distributions of electron beam.

Full textConservative breast surgery followed by radiation therapy is considered the standart treatment for breast cancer. Intraoperative radiation therapy (IORT) has the advantage of decreasing the treatment duration, from the usual 4 to 6 weeks, to a single fraction, delivered during the surgical procedure. The dose distribution for treatment given through IORT are not well known, as the volume to be irradiated is defined at the moment of treatment deliver and there is not a plan optimization routine. Therefore the dose distributions were not, to the moment, the goal of any study, what makes interesting to know them. The goal of the present work is to simulate and compare the IORT dose distribution for different beams and breast geometries, and to compare to the 3D radiation therapy (3DR) dose distribution. The dose distributions for 3DR and for electron beam IORT, generated by the NOVAC7 dedicated accelerator, and for low energy x-ray IORT, generated by Intrabeam dedicated accelerator, were obtained using the Monte Carlo simulation package PENELOPE. The beams validation, performed through comparison with literature data, showed, for the 3DR beam, the dose profile expected for the simulated filters. The greatest differences occurred at the horns region, that appear sub estimated in the simulation. For IORT beams the greatest difference between simulation and literature, of 7.79 and 8.6 percentage points, respectively for the NOVAC7 and Intrabeam, occurred at low depths. The treatment simulation, with three different breast volumes, generated dose distributions that were used for a qualitative comparison of the techniques. 3DR dose distribution showed that a considerable fraction of the dose was delivered to the thorax. Although the highest doses were delivered inside the breast volume, cold regions occurred inside this volume also. Intrabeam dose distributions showed that part of the dose may be delivered to the thorax, given the breast volume and applicator position. The treatment through NOVAC7 presented more homogeneous dose distribution in relation to the other techniques. In general the results indicated that the treatment may be greatly affected by field size and position in 3DR and by the applicator position for both of the IORT techniques. Treatment through low energy x-ray IORT is comparable to 3DR treatment. According to the plan evaluation parameters electron beam IORT could give the best treatment for all the breast volumes evaluated.

Full textDosimetry in brachytherapy is important to assure the conformity between the planned and the delivered dose to the patient. However, the experimental determination of dose is difficult in this technique due the high dose gradient in regions near the source. Hence, polymer gel dosimetry has been studied as a tool to obtain three-dimensional distribution dose for these sources. A report of American Association of Medical Physics, entitled TG-43, proposes a formalism for dose calculation for brachytherapy sources through parameters such as activity, anisotropy and geometry of the source, and the attenuation and radiation scattering produced in the surrounding medium. However, the dosimetric functions needed for dose calculations are not directly determined through experiments. In this concern, the Monte Carlo method has been used in the calculation of these dosimetric funcions in brachytherapy. In the present work, the dosimetric parameters for two brachytherapy sources, 60Co e 192Ir, were determined using Monte Carlo simulation with PENELOPE code, and the dose distributions for the 192Ir source were determined using polymer gel dosimetry with MAGIC-f. Data obtained computationally were compared to literature, showing more than 98% agreement in all parameters for the 60Co source. For 192Ir, differences up to 22% were found to the literature, although when the results of this work were compared to the treatment planning system, a R2 equal to 0,9996 was found to the data fitting adjusting both data. The comparison of simulated dose distributions for 192Ir and those determined with MAGIC-f polymer gel showed that 97% of the points covered by 50% isodose are in agreement when gamma index criteria of 3% and 3 mm was used. These results indicate the potential use of polymer gel dosimetry with MAGIC-f and Monte Carlo simulation with PENELOPE code in dosimetry of high dose rate brachytherapy sources.
