Developing technologies
Our group's research themes are measurement guided
preparation, delivery and follow-up in cancer radiation therapy. We
have a challenging translational focus, actively bridging diverse
blue skies scientific and clinical research. Our current interests
grew from enduring multidisciplinary, collaborative foundations
laid participating in and leading European Framework and UK
Engineering and Physical Sciences Research Council (EPSRC)
projects. These were conducted in concert with The Christie's
ambitious drive towards providing more effective and technically
advanced radiation therapy treatments for its patients.
The primary objectives are to move towards seeing and measuring
a treatment as it is given, dynamically in 3D, including during
irradiation; to ensure setup and delivery to plan, provide the 4D
evidence for tumour targeting and treatment adaptation, and improve
understanding of the impact of changing patterns of motion and
shape on treatments. Post treatment impact and quality of life are
also of increasing interest, following studies of speech, endocrine
and cardiac disruption.
With the help of EPSRC funding for the Metrology Guided
Radiation Therapy (MEGURATH) project, we are exploring dynamic
optical body surface sensing for positional measurement during
irradiation in collaboration with clinical colleagues. We are also
investigating sensing synchronous with enhanced cone beam computed
tomography (CT) scanning so that the impact of actual rather than
assumed external and internal motion and deformations on complex
reconstructive imaging and therapy techniques can be
investigated.
Through the National Institute of Health Research (NIHR) project
K021, funded by the New and Emerging Applications of Technology
(NEAT) initiative, we are developing and clinically evaluating
direct optical data feedback and display to patients, offering them
the opportunity to engage with, and potentially contribute to the
integrity of, their own treatment. The persistent problem of tumour
and organ delineation has been addressed in EPSRC Structure
Creation using Limited Point Topology Evidence in Radiotherapy
(SCULPTER), focussing on the capture of expert clinical delineation
knowledge using 3D statistical shape modelling, and securing an NHS
Innovation Award. This research is now being continued through an
NIHR funded Scientific Fellowship award and will take a closer look
at the correspondence between modelled and real world anatomical
deformations.
With the help of an EPSRC Feasibility Account, our group has
started speculative research into new regularity and structural
parameters needed to characterise the qualities image volumes
ranging from the macro-scale, used for tumour and organ at risk
delineation, to the micro-scale, such as atomic force and confocal
cell microscopy. Our research continues to focus on improving
delivery and therefore efficacy of radiation-based therapy through
application of novel technologies.
