FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment, namely to magnetic induction tomography. Method includes obtaining access to a plurality of measurement results of coil characteristics obtained for a sample by a single coil, which is excited by radio frequency (RF) energy from a source of RF energy, each of the plurality of measurement results of the coil characteristics is obtained by a single coil in one from a plurality of separate locations relative to the sample and correlating the coil position data with each of a plurality of coil measurement results. Coil position data indicate position and orientation of one coil relative to sample for each measurement result of the coil characteristics, gaining access to a model that determines the relationship between coil measurement results obtained with a single coil, and the electromagnetic characteristic of the sample, and the creation of a three-dimensional graph of the electromagnetic characteristics of the sample. System contains a device with a coil, a movement device, a computer system. Coil device comprises one coil having a plurality of concentric conductor turns, each having an excellent radius connected to a radio frequency (RF) energy source. In this case, one coil is configured to obtain a result of measuring the losses in the coil. Moving device is arranged to position one coil relative to sample at a plurality of separate locations relative to sample. Computing system comprises one or more processors and one or more storage devices storing computer-readable instructions, which, when executed by one or more processors, cause the execution of operations by one or more processors. Operations include: obtaining access to a plurality of coil loss measurement results obtained from a single coil excited by radio frequency (RF) energy from a source of RF energy, wherein each of the plurality of coil loss measurement results is obtained by using a single coil in one of a plurality of separate locations relative to the sample, correlating coil position data indicating the position and orientation of one coil relative to the sample for each coil loss measurement result, with each of a plurality of coil loss measurement results, gaining access to a model defining the relationship between coil measurement results obtained with a single coil, and the specific conductivity of the sample, creating a three-dimensional graph of the conductivity of the sample using a model based at least in part on the set of coil loss measurement results and coil position data associated with each measurement result of the coil characteristics. System also includes one or more material permanent machine-readable media storing machine-readable instructions, which, when executed by one or several processors cause the operations for magnetic induction tomography of the sample to be performed by one or several processors.
EFFECT: use of the group of inventions allows to expand the range of means for magnetic induction tomography.
