Integrated system for driving and location recognition of mobile magnetic substances

An integrated system for driving a magnetic body and recognizing a position thereof, the system comprising:

• a magnetic field generating unit comprising four electromagnetic coils radially spaced apart from each other by an identical distance, and a coil frame to which the electromagnetic coils are connected;
• an RF coil unit disposed in a through-hole included in a central portion of the coil frame;
• a driving unit orthogonal to the coil frame and connected to allow the coil frame to slide in one axial direction;
• and
• a processing unit configured to generate movement path information of the coil frame and desired current information of each of the four electromagnetic coils;
• wherein a central axis of each of the four electromagnetic coils is directed toward the center of the coil frame,
• wherein the driving unit moves the coil frame according to the movement path information, and
• wherein the processing unit is configured to generate a field free point (FFP) or a field free line (FFL) through the magnetic field generating unit, set a first scan path that is a movement path of the field free point or the field free line, scan the magnetic body along the first scan path, receive a first reflection signal reflected from the magnetic body, and identify a first position of the magnetic body, which is a position on the Z-axis perpendicular to the magnetic field generating unit, by using the first reflection signal.
