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 s
