Biomedicine is one of the directions of modern science, where a particular problem of noninvasive human studies. One of the di-rections of modern science, where the problem of noninvasive human research is particularly acute, is biomedicine. Hidden foreign ferromagnetic inclusions in the human body are either foreign bodies that penetrated into its tissues, organs and cavities through damaged covers or through natural openings, or joint prostheses surgically implanted in the body with a curative purpose, binding bone fragments of the spoke, rods, plates etc. Identification of such inclusions, is sometimes a rather laborious process, because At the moment, the solution to this problem is carried out for the most part by non-invasive methods of introscopy. In practice, carrying out human studies using these methods is not always possible, for example, when examining the patient's head.
To ensure reliable and safe research, it is necessary and required to perform a set of physically different methods, techniques and technical means that lead the research process to an increased and sometimes unjustified time, material and human resource.
As an alternative solution for detecting inclusions, magnetic research is increasingly being used, which now, according to it, is one of the effective reserves for improving quality, reliability and safety, and is also on the next stage of development.
In this regard, the effectiveness of solving these problems is inextricably linked with the increase in the level of equipment with technical means. A special place among them belongs to systems that realize the solution of the declared problems. Infor-mation-measuring systems, allowing to carry out non-destructive magnetic research, have recently acquired increasing importance. The number of such systems is still small, as indicated by the small number of patents.
Thus, the modified model of the precision measuring coils and the positioning device for the information-measuring system of the noninvasive magnetic induction study of ferromagnetic inclusions of biological objects is proposed in the work. The resolution of the system is evaluated through active field experiment.
