description |
The goals of this work are: (1) To evaluate a plastic scintillation detector and other stereotactic dosimeters for measuring output factors, dose profiles and percent depth dose curves of small and sub-centimeter radiation fieldsand (2) to obtain tables of K fclin,fmsr Qclin,Qmsr correction factors based on Monte Carlo simulations using codes BEAMnrc and DOSXYZnrc.Tables of output ratios and dose profiles for radiation fields conformed by a micro-multileaf collimator were obtained for the stereotactic detectors: 1) Standard Imaging W1 Exradin Plastic Scintillation Detector with 1 mm diameter and 3 mm length, 2) PTW dosimetry diode E type 60017 with 1.13 mm diameter and 30 µm thickness and 3) PTW Pinpoint 31016 3D ionization chamber with 3.13 mm diameter.Monte Carlo BEAMnrc simulations were performed for the 6 MeV energy of a Varian Clinac iX linear accelerator with the micro-multileaf collimator attached to its gantry. The OSXYZnrc Monte Carlo code was used to calculate the output factors Ωfclin,fmsr Qclin, Qmsr ,water MC and the dose profiles in a virtual water phantom by means of the phase space file obtained from the BEAMnrc simulation. The K fclin,fmsr Qclin,Qmsr factor tables presented in this work show that for field sizes with radius larger than the range of secondary charged particles, the corrections for the set of detectors are lower than 7 % compared with Monte Carlo calculations. However, for sub-centimeter radiation fields, the corrections are about of 23 % for the PTW Pinpoint ionization chamber and up to 12 % for the rest of detectors. |

Se realizaron simulaciones mediante el código de Monte Carlo BEAMnrc del acelerador lineal de marca Varian Clinac iX para su energía en fotones de 6 MeV con un colimador adicional micromultiláminas acoplado al gantry. El código de Monte Carlo DOSXYZnrc se usó para calcular los valores de output factor denotados como Ω fclin,fmsr Qclin,Qmsr ,waterM C y los perfiles de dosis en un fantoma virtual de agua y por medio del archivo de espacio de fase obtenido de la simulación BEAMnrc.Las tablas de los factores K fclin, fmsr Qclin, Qmsr presentadas en este trabajo muestran que para tamaños de campo de radiación con radios mayores que el rango de las partículas cargadas secundarias, las correcciones para el conjunto de detectores son menores al 7 % comparados con los cálculos de Monte Carlo. Sin embargo, para campos de radiación sub-centim´etricos, las correcciones son de alrededor del 23 % para la cámara de ionización Pinpoint PTW 31016 y hasta del 12 % para el resto de los detectores.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Físicahttps://revistas.unal.edu.co/index.php/momento/article/view/66140Universidad Nacional de Colombia Revistas electrónicas UN MOMENTO - Revista de FísicaMOMENTO - Revista de FísicaMachado, Norman H. and Restrepo, Johans (2017) K fclin,fmsr Qclin,Qmsr CORRECTION FACTORS OF PLASTIC SCINTILLATORS AND OTHER STEREOTACTIC DETECTORS FOR SUB-CENTIMETER PHOTON FIELDS USING MONTE CARLO.
