Summary on Grant Application Form |
|
A non-contacting electrical impedance imaging system for biological tissues will be developed in which the coupling to the tissue will be magnetic. Coils will be used to induce currents in the tissue and to detect the resulting perturbations in magnetic field. This technique has been termed 'magnetic induction tomography (MIT). No one has yet obtained MIT images of biological tissues, either in vivo or in vitro. Preliminary work carried out in our laboratory at 10MHz, has obtained measurements on saline solutions with conductivities in the tissue range (0.02-2S/m) which agreed well with theoretical predictions. Initially this work will be extended by constructing a dedicated single-channel system, and then a multiple-coil, electronically-scanned system will be designed and constructed. Computer simulations will be performed enabling (i) the measured results to be compared with theory, (ii) evaluation of different image reconstruction algorithms, (iii) prediction of the required sensitivity for detecting different pathological conditions, and (iv) comparison of images with those obtained by conventional injected-current EIT techniques. A clinical MIT system could offer exciting new possibilities in medical imaging because it would not suffer from the inconvenience of having to attach a large number of surface electrodes to the patient.
