Radiotherapy Physics

A man using a high-tech piece of equipmentApproximately 3,000 radiotherapy patients each year are treated in Oxford. The links with clinical oncology are strong, and we foster a multidisciplinary, collaborative approach to the care of cancer patients, between oncologists, physicists, radiographers, technologists and clerical staff.

We also collaborate withthe University of Oxford, in particular the Gray Institute for Radiation Oncology and Biology.

A woman using a screenIn the Cancer and Haematology Centre we have:

  • six matched linear accelerators with intensity modulated radiotherapy (IMRT) capability, MV portal imaging and real-time position management (RPM gating). Two of these linear accelerators also have kV image guidance and cone beam CT
  • a Pulsed Dose Rate (PDR) brachytherapy afterloader
  • CT scanner for radiotherapy planning and simulator with CBCT.

Services we provide

  • Dosimetry and calibration.
  • Expert advice on optimisation of treatment planning, verification and delivery. (Conformal using multi-leafed collimators (MLC) and field-in-field.)
  • Equipment quality assurance.
  • In-vivo dosimetry using diodes and thermo-luminescent dosimeters.
  • Support of imaging for radiotherapy planning and verification. This includes MR-CT fusion.
  • Total body irradiation (TBI).
  • The Oxford Cancer and Haematology Centre also host a positron emission tomography (PET) service. This is used to guide radiotherapy planning.
  • Training radiotherapy physicists as part of the NSHCS Scientists Training Programme
  • Training for the IPEM clinical technologist training scheme.

Development work

  • National and international clinical trials.
  • IMRT.
  • Respiratory motion management to facilitate 4D treatment planning and gated treatment delivery.
  • Clinical radiobiology.
  • Field-in-field planning for TBI.
  • Introduction of interstitial fiducial markers to aid image guidance and the application of on-line set-up correction protocols.
  • Extension of image fusion to other clinical sites, and other imaging modalities.
  • Optimisation of image quality across the radiotherapy pathway.
  • Development of IQWorks image analysis software.
  • Development and hardening of radiotherapy information systems infrastructure.
  • A comprehensive guide to the provision of a physics service to radiotherapy can be found on the Institute of Physics and Engineering in Medicine (IPEM) website.
