FIELD: medicine.
SUBSTANCE: capsule endoscope control system comprises: the first inductor coil assembly with coil sections attached to three axes at right angles to each other and generating magnetic fields in respective axial directions; the second inductor coil assembly arranged so as to generate a gradient magnetic field in any direction relative to the magnetic field generated by the first inductor coil assembly; a drive unit for the inductor coils to drive the second inductor coil assembly to adjust the gradient magnetic field orientation; a control unit comprising a receiving portion to receive an image signal transmitted from the capsule endoscope and a control portion, regulating the electric currents supplied to the first and second inductor coil assemblies to control the generated magnetic field and control the inductor coils drive unit; and a capsular endoscope containing two permanent magnets located at right angles to each other and creating magnetization with a magnetization vector located at an angle with respect to the longitudinal direction of the capsule endoscope body in the range of acute angles (0<δ<90°). At that, the capsule endoscope precesses under the influence of the rotating magnetic field generated by the first inductor coil assembly, and moves along the spiral path along the tubular body under the action of the gradient magnetic field generated by the second inductor coil assembly acting together with the said magnetization. The capsule endoscope system includes a system and a camera module to capture images and transmit them to the outside. The capsule endoscope is capable of moving along a spiral path along the inner side of the tubular body under the action of the rotating magnetic field and gradient magnetic field generated from outside.
EFFECT: improved accuracy of tubular body wall condition diagnosis.
