Multiscale multiphysics tomography
by: Dr Manuchehr Soleimani (University of Bath).
New and emerging tomographic methods enable us to explore and study objects with various physical measurement techniques. Examples include
electromagnetic tomography such as EIT, ECT, MIT, optical tomography, mechanical imaging method such as ultrasound tomography and elastic tomography.
Most of the new and emerging tomographic techniques are cost effective and integratable. Each of these imaging methods has their own disadvantages such as low sensitivity in certain areas of the object, low resolution and so on. However each of them also has their own advantages. The multiphysics tomography concept uses the complimentary properties of combined imaging methods to image an object. One way to improve the image quality is using these imaging techniques in multimodality mode. In this talk we present some examples of multimodality tomography and show the improvement compared to individual modes.
These techniques also could be used in a wide range of applications on different scales; body, organ and cell imaging, for example. It is not yet clear how a unified multiscale method would work. In fact, a challenging mathematical formulation would be to develop a multiscale inversion technique.
Tomographic methods by their very nature are multi-disciplinary across the disciplines such as maths, physics, engineering, biology, medicine and geophysics. So we hope that this presentation will allow us to identify new areas of multi-disciplinary research.
