Claim:
1. An electromagnetic tomography (EMT) system for gathering measurement data pertaining to a human head, comprising: (a) an image chamber unit including an antenna assembly at least partially defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber, the array of antennas including at least some transmitting antennas and at least some receiving antennas; (b) a control system that causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a human head in the imaging chamber and produces a data tensor, from resulting signals, that may be inversed to reconstruct a 3D distribution of dielectric properties within the human head and thereby to create an image of the head; (c) a housing, at least partially containing the antenna assembly, having a front entry opening into the imaging chamber; and (d) a flexible membrane that substantially liquid-seals the front entry opening such that a front portion of the imaging chamber is separated from a rear portion of the imaging chamber; (e) wherein the head of a human patient may be inserted horizontally through the front entry opening and into the imaging chamber.
