Medical Physics

The application of physics in medicine and health-related problems is a major area of research in the Department of Physics and has an established international reputation.  Many of the methods developed in these areas also have potential for industrial applications, which is an exciting aspect of the research performed at Surrey. 

Improving Contrast in X-ray images using spectroscopic imaging

Better Contrast in medical imaging using contrast agents is possible by energy gating of the X-ray signal, an example is shown below.

Dosimetry and Health Physics

Silica based fibre dosimeters offer high spatial resolution, low cost, easy handling (compared to established dosimeter materials – TLD 100), and are bone equivalent.

 Different type geometry silica fibre thermoluminescent (TL) signals (Ghomeishi at al, Scientific Reports 5,13309 (2015))

Improving Radiotherapy

Improving Radiotherapy by

  • Treatment Modalities
  • Quality assurance/Dosimetry
  • Reducing dose to healthy tissue 

Left: Increased risk of acute coronary events due to irradiation of the heart during radiotherapy of breast cancer (women over 50 years) (Darby et al. N Engl J Med 2013; 368:987-998 (2014)), Right: SEM of a Nano SQUID device, microdosimeter development (Galer et al., Radiat Prot Dosimetry 143(2-4), 427-431(2011))
