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： 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 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 interface image based on the undisturbed electromagnetic interference image, recognizing electromagnetic interference patterns in the repeatedly formed disturbed electromagnetic interface images, and forming a superposition image by nullifying or diminishing the recognized electromagnetic interference patterns from the disturbed electromagnetic interface image. Forming a disturbed electromagnetic interface image is also based on an object factor that is a functional 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 assessing status of a biological tissue includes irradiating an electromagnetic signal, via a probe, into a biological tissue. The irradiated electromagnetic signal is received after being scattered/reflected by the biological tissue. Blood flow information pertaining to the biological tissue is provided, and the received signal is analyzed based at least upon the provided blood flow information and upon knowledge of electromagnetic signal differences in normal, suspicious, and abnormal tissue. Using a dielectric properties reconstruction algorithm, dielectric properties of the biological tissue are reconstructed based at least upon results of the analyzing step and upon blood flow information, and using a tissue properties reconstruction algorithm, tissue properties of the biological tissue are reconstructed based at least in part upon results of the reconstructing step and upon blood flow information.
