Abstract:
1. A method of electrical impedance imaging comprising: using multiple recessed electrodes in which each of the multiple recessed electrodes does not contact an object to be imaged but is electrically coupled to the object via an electrically conductive fluid in which the object is at least partially immersed; using a housing for the recessed electrodes to contain the fluid and varying dimensions of the housing to correspond to the size of the object: wherein a first housing portion has a first plurality of recessed electrodes and a second housing portion has a second plurality of recessed electrodes and wherein relative movement of the first housing portion and the second housing portion varies a proportion of the second plurality of recessed electrodes that are exposed for electrical coupling to the object via the electrically conductive fluid in which the object is at least partially immersed.
