Abstract: An electromagnetic tomographic scanner, for use in imaging a live human body part, includes an imaging chamber, a plurality of antennas, a controller, a lid, and a quantity of matching media. The imaging chamber is supported on the base, defines an imaging domain in that receives the head, and has an open end. The antennas are supported by the imaging chamber and encircle the imaging domain. The controller controls one or more antenna. The lid is attachable to the open end and includes a hollow boundary model that mimics a part of human anatomy that is outside the imaging domain. The matching media fills the interior of the model while an empty field measurement is carried out. Various tensors may be produced.

Abstract: An electromagnetic tomographic system for imaging a human head includes a base, an imaging chamber, at plurality of antennas, a plurality of antenna controllers, and an image processing computer system. The imaging chamber is supported on the base and defines an imaging domain in that receives the head. The antennas are supported by the imaging chamber and encircle the imaging domain. Each controller is dedicated to a respective antenna and includes RF transceiver circuitry having a transmit side and receive side that are alternately connected to the antenna using an RF switch. In operation, while one antenna is transmitting an electromagnetic signal into the imaging domain, a plurality of the antennas are simultaneously receiving the signal after passing through the imaging domain. The received signals of the plurality of antennas are simultaneously measured. Data representative of the measure electromagnetic signals is output by the controllers and used for image processing.

Abstract: An electromagnetic tomographic system for imaging a human head includes a base, an imaging chamber, at least one ring of antennas, a plurality of antenna controllers, and an image processing computer system. The imaging chamber is supported on the base and defines an imaging domain in which the head is received. The antennas are supported by the imaging chamber and encircle the imaging domain. Each antenna controller includes radio frequency (RF) transmitter/receiver circuitry that is connected to an antenna, an intermediate frequency (IF) stage, and a baseband (BB) data processing stage. Data representative of the measure electromagnetic signals is output by the controllers and used for image processing.
