Medical physics

The application of physics in medicine and health-related problems is a major area of research in our group as well as our Department of Physics as a whole 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 here 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.

Dosimetry and health physics

Research impact

Silica based dosimeters offer high spatial resolution, low cost, easy handling (compared to established dosimeter materials) and are bone equivalent. We have pioneered the use of micro silica beads for medical dosimetry, leading to the foundation of the spin out company Trueinvivo, to ensure that the new technology will be available to the benefit of patients as soon as possible.

Current work

We are currently focusing on translating the technology to clinic's, as well as demonstrating its uses in other industrial applications that require higher doses.

Irradiation

Improving radiotherapy

The key aspects we are working on to improve radiotherapy are exploring new treatment modalities by improving quality in dosimetry and reducing the dose that goes to healthy tissues.

Personalised and biologically optimised treatment planning in radiotherapy

Significant improvement in cancer treatment by radiotherapy can be achieved by taking into account the radiobiological response of cells, tissues and patients to radiation exposures.

Technological development of the last decades has provided a variety of radiotherapy approaches such as:

  • Stereotactic ablative radiotherapy (SABR)
  • MR-guided radiotherapy
  • Proton and hadron therapy
  • High dose rate radiation beams.

The biological effects of such irradiation modalities vary greatly requiring a better understanding of radiobiological mechanisms and new models.

Current research

The key aspects of work we are currently researching are:

  • Microdosimetry for proton and hadron beams
  • Radiobiological modelling
  • Dosimetry and quality assurance for pre-clinical studies
  • Radiosensitisation by high-Z nanoparticles.

Group research

We work across three other research areas here in the Radiation and Medical Physics Group.
