Synopsis
Electrical Impedance Tomography is a relatively new imaging method that traditionally uses a ring of external electrodes to image impedance changes in 2D within the body. The technology has recently
been described as being on the verge of clinical application for pulmonary monitoring with medical device manufactures offering 2D imaging systems for trial (Bodenstein et al, Critical Care Medicine,
2009). There is also clinical need to image the heart in intensive care but physicians find echocardiograms difficult due to the presence of bone and the ventilated state of the lungs. The resolution of EIT is limited by the number of measurements, electrode location and the 2D nature of acquisition. For providing the optimum information on cardiac function it is important to measure a sufficient number of frames within a single cardiac cycle. In collaboration with clinicians at Westmead hospital this project will aim to increase the measurement speed, use of internal electrodes and other methods to improve image resolution.
