摘要： An Electromagnetic Interference Pattern Recognition Tomography (EMIPRT) method for use in an image reconstruction system includes generating electromagnetic field data corresponding to an object in an imaging domain, via an electromagnetic tomography system, and using the generated electromagnetic field data, repeatedly, in recursive manner, forming an undisturbed electromagnetic interference image, forming a disturbed electromagnetic interference image based on the undisturbed electromagnetic interference image, recognizing electromagnetic interference patterns in the repeatedly formed disturbed electromagnetic interference images, and forming a superposition image by nullifying or diminishing the recognized electromagnetic interference patterns from the disturbed electromagnetic interference image. Forming a disturbed electromagnetic interference image is also based on an object factor that is a function of the differences between experimentally electromagnetic fields and electromagnetic fields calculated during the step of forming an undisturbed electromagnetic interference image. After each repeated step of forming a superposition image, the method also includes determining whether a convergence objective has been reached.

摘要： A method of identifying and locating tissue abnormalities in a biological tissue includes irradiating an electromagnetic signal, via a probe defining a transmitting probe, in the vicinity of a biological tissue. The irradiated electromagnetic signal is received at a probe, defining a receiving probe, after the signal is scattered/reflected by the biological tissue. Blood flow information pertaining to the biological tissue is provided. Based on the received irradiated electromagnetic signal and the blood flow information, tissue properties of the biological tissue are reconstructed. A tracking unit determines the position of at least one of the transmitting probe and the receiving probe while the step of receiving is being carried out, the at least one probe defining a tracked probe. The reconstructed tissue properties are correlated with the determined probe position so that tissue abnormalities can be identified and spatially located.

摘要： An electromagnetic tomography system for gathering measurement data pertaining to a human head includes an image chamber unit, a control system, and a housing. The image chamber unit includes an antenna assembly defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber. The antennas include at least some transmitting antennas and some receiving antennas. The control system causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a patient's head in the imaging chamber. A data tensor is produced that may be inversed to reconstruct a 3D distribution of dielectric properties within the head and to create an image. The housing at least partially contains the antenna assembly and has a front entry opening into the imaging chamber. The head is inserted horizontally through the front entry opening and into the imaging chamber.

摘要： 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 controller comprises circuitry carried on a printed circuit board and is dedicated to a respective antenna. Each controller controls operation of a corresponding antenna. 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.

摘要： 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.

摘要： A method of identifying and locating tissue abnormalities in a biological tissue includes irradiating an electromagnetic signal, via a probe defining a transmitting probe, in the vicinity of a biological tissue. The irradiated electromagnetic signal is received at a probe, defining a receiving probe, after the signal is scattered/reflected by the biological tissue. Blood flow information pertaining to the biological tissue is provided. Based on the received irradiated electromagnetic signal and the blood flow information, tissue properties of the biological tissue are reconstructed. A tracking unit determines the position of at least one of the transmitting probe and the receiving probe while the step of receiving is being carried out, the at least one probe defining a tracked probe. The reconstructed tissue properties are correlated with the determined probe position so that tissue abnormalities can be identified and spatially located.
