A new surgical navigation technology of active magnetic positioning of moving objects is described. The studies showed the readiness of this innovative technology for clinical implementation. Assessment shows the possibility of creating an alternative to system Carto XP, widely used in Russia for cardiothoracic surgery. Active magnetic positioning of moving objects is performed by measuring induction with special sensors placed with known spacing on the surface of an object located in a specially created inhomogeneous magnetic field [1]. Special organization of the magnetic field enables calculation of the position and orientation of the object based on the results of measurements performed by a moving receiver rover. Advantages of magnetic field to other fields, such as acoustic, optical, radio frequency, gravitational, and electric are maximum velocity of propagation, high-linear gradients, low noise, and small size of measuring tools. Only stationary magnetic field allows working in confined spaces due to minimal impact of interior and environment. So, this field is less affected than others by distortion when the line of sight between the source and receiver is closed by a moving object. Particularly, the human body is not an obstacle for the magnetic field. Thus, stationary magnetic field can be used for small distance navigation in confined spaces.
