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 and Switzerland 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 completed her MSc in 2015. Elizabeth has demonstrated particular interest and experience in advanced treatment planning; specifically VMAT, IMRT 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.

  • 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.
