Job Description

Are you interested in contributing to the world’s first thermal breast tomography system to be developed at Leeds University that could revolutionise the way women are scanned for breast cancer? Would you like to develop your cross-cutting research capabilities in: Novel Imaging Technologies, Novel Computational and Mathematical Sciences, and Medical Device Design and Innovation?

Any tomography technique has at its heart a difficult inverse problem that needs to be solved, hence the mathematical analysis on the well or ill-posedness of the model is necessary to be undertaken for scientific justification, as well as to be able to improve it. Difficulties arise due to the non-existence, non-uniqueness or the instability of solution, and establishing the degree of ill-posedness of the operator that needs inverting, is non-trivial. Moreover, concerning the actual inversion, to detect buried/hidden objects based on the transient approach one has to solve a difficult nonlinear and ill-posed moving boundary problem, which leads to a non-convex multi-dimensional optimization that needs to be further regularized to achieve stable results.

The thermographic principle of taking surface temperature measurements as we dynamically heat or cool an object offers an interesting transformative idea, but the approach is yet to be tested in an uncontrolled environment. Therefore, this mathematical modelling project using thermal-waves will provide a solid platform on which improved instrumentation for imaging can be built.

The aim is to mathematically model a tomographic system capable of scanning the interior of a body from transient boundary data. As such, transient data contains much richer information on the unknowns than the steady-state stationary measurements. The objectives of this project (together with the supervisor) you will:
