Aims of the programme

  • To promote research in dosimetry with the emphasis on its application in medical physics and healthcare.
  • To study the application of Monte Carlo simulation of radiation transport to radiotherapy and medical imaging.
  • To keep high quality and reliability levels in the Calibration and Dosimetry Laboratory and in the Thermoluminescence Dosimetry Laboratory.
  • To ensure adequate dosimetric monitoring of the staff who are professionally exposed at the UPC.
  • To organise and participate in postgraduate courses and lifetime training within the field of radiological protection and dosimetry.

Current Research Projects

  • SYRA3 - Innovative Methods in Radiotherapy and Radiosurgery using Synchrotron Radiation
    EU COST Action TD1205 (2013 -2017)
    Josep Sempau
    Innovative Methods in Radiotherapy and Radiosurgery using Synchrotron Radiation (SYRA3) is a COST Action in the Biomedicine and Molecular Biosciences domain. Its aim is to setup and coordinate a multidisciplinary network to develop synchrotron radiotherapy and radiosurgery techniques to treat brain tumours and other diseases of the central nervous system. The official SYRA3 COST page (Action TD1205) can be reached at http:\\www.syra3.eu.
  • EURADOS Working group 12 - (2013-2016) “Medical imaging dosimetry”
    Mercè Ginjaume

    The working group deals about optimization of radiation protection for patients and workers in the medical field. In particular the following topics are studied: Patient skin dosimetry with Gafchromic films, Developments in patient dosimetry for patient dose optimization and risk estimations in Interventional Radiology and CT, Eye lens dosimetry for medical staff.

  • PRIMO - Advanced tools for linac simulation. Ministerio de Economía y Competitividad ref. FIS2012-38480 (2013-2016)
    Josep Sempau

    The project aims at developing automated software tools that allow simple and fast Monte Carlo simulation of a wide range of clinical linear accelerators (linacs) currently available in the market for radiotherapy treatments. We work in collaboration with researchers from the Universitätsklinikum Essen in Germany and from the Karolinska Institutet in Stockholm.
  • SDASIMRT - Skin dose assessment in radiation therapy treatments (RT) with modulated intensity (IMRT)
    Maria A. Duch

    The aim is to determine the dose to the skin for external RT. Skin dose distributions for standard techniques will be compared with those for IMRT. The accuracy of the dose calculation in this region using different algorithms as implemented in treatment planning systems will also be studied. An accurate determination of the skin dose, either experimentally or with the aid of computational tools such as Monte Carlo simulation, is important both for using realistic dose-surface or dose-volume constraints in dose optimisation engines for IMRT and, also, to allow accurate predictions of toxicity during treatment, and therefore design strategies to minimize it.
