His area of research interest is in quantitative functional imaging using radionuclide tracers – SPECT (Single Photon Emission Computed Tomography) and PET (Positron Emission Tomography). He has been a pioneer of hybrid imaging of structure (morphology) and function (physiology) combining multiple modalities into a single imaging session. With the increasing utilisation of radionuclide therapies in cancer management in recent years, Dale has turned his attention to the biological effects of radiation and quantifying radiation dosimetry to tissues to personalise individual treatments and improve patient outcomes.
