A general analytical solution to the geometrical problem of field matching in radiotherapy
(2009)
Article
Restricted access - publisher's policyPurpose: Several authors studied the problem of geometrical matching of fields produced by medical linear accelerators. However, a general solution has yet to be published. Currently available solutions are based on ... -
A method for accurate zero calibration of asymmetric jaws in single-isocenter half-beam techniques
(2013-02)
Article
Restricted access - publisher's policyPurpose: To present a practical method for calibrating the zero position of asymmetric jaws that provides higher accuracy at the central axis and improves dose homogeneity in the abutting region of half-beams. Methods: ... -
Cuantificación de la dosis en superficie en radioterapia: Simulación Monte Carlo y medidas con cámara de extrapolación
(Universitat Politècnica de Catalunya, 2013-05)
Master thesis
Open AccessDuring a radiotherapy treatment, skin of the patient is always exposed to the radiation; as a consequence late effects can be appear. Therefore, dose values in this region may be of interest for clinical evaluation and ... -
Determinación de dosis periféricas en tratamientos de radioterapia externa
(Universitat Politècnica de Catalunya, 2010-07)
Master thesis
Open AccessHoy en día el cáncer es una de las principales causas de muerte en nuestra sociedad. Como consecuencia durante los últimos años se han desarrollado nuevas técnicas y modalidades de radioterapia para hacer frente a esta ... -
Dose variations in tumor volumes and organs at risk during IMRT for head-and-neck cancer
(2012)
Article
Open AccessMany head-and-neck cancer (HNC) patients treated with radiotherapy suffer significant anatomical changes due to tumor shrinkage or weight loss. The purpose of this study was to assess dose changes over target volumes and ... -
Estimación de la dosis absorbida mediante dosimetría termoluminiscente en exploraciones de RX de localización para tratamientos de radioterapia
(Universitat Politècnica de Catalunya, 2010-07)
Master thesis
Open AccessEl objetivo del proyecto consiste en estimar la dosis absorbida en una exploración de RX de localización utilizada en radioterapia guiada por la imagen. Para estimar la dosis se ha utilizado un sistema de dosimetría basado ... -
Experimental verification of acuros XB in the presence of lung-equivalent heterogeneities
(2017-11)
Article
Open AccessAcuros XB (AXB) is a deterministic algorithm that directly accounts for the effects of heterogeneities and improves the accuracy of photon dose calculations in radiotherapy. Nevertheless, the accuracy of AXB inside lung ... -
Failure mode and effect analysis oriented to risk-reduction interventions in intraoperative electron radiation therapy: The specific impact of patient transportation, automation, and treatment planning availability
(2014-11-24)
Article
Restricted access - publisher's policyBackground and purpose: Industrial companies use failure mode and effect analysis (FMEA) to improve quality. Our objective was to describe an FMEA and subsequent interventions for an automated intraoperative electron ... -
Monte Carlo and experimental small-field dosimetry applied to spatially fractionated synchrotron radiotherapy techniques
(Universitat Politècnica de Catalunya, 2012-03-12)
Doctoral thesis
Open AccessTwo innovative radiotherapy (RT) approaches are under development at the ID17 Biomedical Beamline of the European Synchrotron Radiation Facility (ESRF): microbeam radiation therapy (MRT) and minibeam radiation therapy ... -
Monte Carlo-based dose calculation engine for minibeam radiation therapy
(2014-02)
Article
Restricted access - publisher's policyMinibeam radiation therapy (MBRT) is an innovative radiotherapy approach based on the wellestablished tissue sparing effect of arrays of quasi-parallel micrometre-sized beams. In order to guide the preclinical trials in ... -
PENELOPE/PRIMO-calculated photon and electron spectra from clinical accelerators
(Springer (Biomed Central Ltd.), 2019-01-11)
Article
Open AccessBackground: The availability of photon and electron spectra in digital form from current accelerators and Monte Carlo (MC) systems is scarce, and one of the packages widely used refers to linacs with a reduced clinical use ... -
