Actuation control system of a capsule endoscope

摘要

A system for controlling actuation of a capsule endoscope includes a receiving unit receiving an image transmitted from the capsule endoscope; a coil unit generating a magnetic field for actuating the capsule endoscope by using current applied thereto; a power supply unit supplying power to the coil unit; and an actuation controller control the current applied to the coil unit and a coil rotational motor for adjusting of a posture and the location of the capsule endoscope based on the identified lesion or location of the capsule endoscope, wherein the coil unit includes a pair of Helmholtz coils and a pair of Maxwell coils that are fixedly disposed on a main axis; and a pair of uniform saddle coils and a pair of gradient saddle coils that are located inside the pair of the Helmholtz coils and the pair of the Maxwell coils to rotate around the main axis.

1. A system for controlling actuation of a capsule endoscope, the system comprising:
a receiving unit receiving images transmitted from the capsule endoscope; a coil unit generating a magnetic field for actuating the capsule endoscope by using applied current thereto; a power supply unit supplying power to the coil unit; and an actuation controller identifying lesion or a location of the capsule endoscope based on the images received through the receiving unit and controlling a motor for controlling the current applied to the coil unit and a posture and the location of the capsule endoscope based on the identified lesion or location of the capsule endoscope, wherein the coil unit comprises
a pair of Helmholtz coils fixedly disposed on a main axis,a pair of Maxwell coils fixedly disposed on the main axis,two pairs of uniform saddle coils located inside the pair of the Helmholtz coils and the pair of the Maxwell coils and fixedly disposed on a plane perpendicular to the main axis, the two pairs of the uniform saddle coils being disposed to be orthogonal to each other and not rotating about the main axis, anda pair of gradient saddle coils disposed inside the pair of the Helmholtz coils and the pair of the Maxwell coils and rotating about the main axis.
