MAGNETIC INDUCTION TOMOGRAPHY METHOD Russian patent published in 2019 - IPC A61B5/55 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to magnetic induction tomography methods. Method includes arrangement of object and magnetic field receivers in space, excitation of magnetic field in this space, measurement of eddy currents induced by this field in magnetic field receivers, and reconstruction of image of spatial distribution of conductivity of object based on measurement results, wherein creating the magnetic field induction vector crossing the analyzed object from the total magnetic flux generated by the magnetic field sources, wherein measurement of eddy currents induced by magnetic field in the investigated object is carried out along the axis of the flexible magnetic conductor connected to the magnetic field source. Measurement of eddy currents induced by the magnetic field source in the investigated object is performed with the possibility of arbitrary rotation of the magnetic field induction vector during its rotation around an arbitrary axis. Reconstruction of the conductivity of the object is carried out based on the results of comparative measurements in the absence and presence of an object in the analyzed space, wherein the zone for changing the sign of the vector of magnetic field induction is shifted beyond the limits of the investigated space.

EFFECT: high efficiency of using magnetic field sources.
