Mrs. Elizabeth Forde
Assistant Professor, Radiation Therapy


A graduate of The University of Sydney, Elizabeth has over 10 years of clinical experience as a Radiation Therapist. She has worked clinically in Ireland, The UK, and Australia and has spent time in The US, Switzerland and Italy in a research capacity. In 2011 Elizabeth relocated to Ireland where she was appointed as Assistant Professor in the Discipline of Radiation Therapy in 2012 and was awarded a MSc in 2015. Elizabeth is currently completing her PhD in quantitative imaging analysis and its application to the prediction of radiation induced normal tissue damage. Elizabeth has demonstrated particular interest and experience in advanced treatment planning and image guided adaptive radiotherapy. Her involvement in a number of clinical schools and education symposiums has allowed Elizabeth to develop her enthusiasm for teaching. In 2017 she joined the editorial board for the Journal of Medical Imaging and Radiation Sciences and 2019 became a member of council for the Irish Institute of Radiography and Radiation Therapy. Elizabeth is also a long standing faculty member of the ASMR ESTRO course and is also an ESTRO FALCON tutor.

  • Summary
    • This specific funded project forms part of a larger piece of research relating to the Quantitative Imaging Analysis of Radiation Induced Normal Tissue Damage
  • Funding Agency
    • ESTRO (Mobility Grant)
  • Date From

  • Title
    • The dosimetric impact of an "off-axis" contour variation when treating prostate radiotherapy with intensity and volumetric modulated fields
  • Summary
    • Due to the modulated nature of the fields, a volumetric approach to contour variation is essential when treating with either IMRT or VMAT. The traditional central axis measurement is no longer sufficient as an indicator for dosimetric variation on target dose and fails to inform of the need for plan adaptation. This reseach quantifies the impact a body contour variation may have on the dose to the target for prostate radiotherapy.
