The tracer 140 is provided in various types, for example, the tracer 140 is an infrared emitter, and coordinates of a positioning area are confirmed by identifying the infrared emitter through an external navigation system; or, the tracer 140 is an infrared reflective ball, and the reflective ball is used for reflecting infrared light, so that an external navigation system can identify the reflected light to determine the coordinates of the positioning area; further alternatively, the tracer 140 may be a GPS tracer, etc., as long as the tracer 140 can acquire the coordinates of the tracer 140, and the coordinates of the location area can be determined by the coordinates of three or more tracers 140.

In addition, a sensing switch 150 is disposed in the positioning region, and the sensing switch 150 is used for controlling the turn-on and turn-off of the tracer 140. When needs use tracer 140, inductive switch 150 control tracer 140 opens, and when the location finishes, inductive switch 150 control tracer 140 closes, avoids tracer 140 to be in the waste that leads to electric power resource of the on-state for a long time, can also improve tracer 140's life simultaneously. It is understood that the inductive switch 150 may not be disposed in the positioning area, and the tracer 140 may be controlled to be turned on or off by a controller or a remote controller in other manners.

There are various methods of setting the imaging device, for example, when the imaging device is a C-arm in a medical instrument. The C-shaped arm is provided with an image intensifier 300, and the image intensifier 300 is used for acquiring an image of an affected part of a patient in the orthopedic operation process. When applied to a C-arm, the tracking structure is used to indicate the spatial position of the image intensifier 300. And an external optical tracking system is typically used when using the tracking structure to indicate the spatial position of the image intensifier 300.

In particular, during use, the tracking structure is sleeved outside the image intensifier 300, and at this time, the relative positions of the tracking structure and the image intensifier 300 are fixed and known, that is, the relative positions of the hollow space 120 and the image intensifier 300 are fixed and known. The optical tracking system is capable of identifying the spatial coordinates of each tracer 140, thereby determining the spatial location of the localization area from the coordinates of three or more tracers 140; while the relative position between the positioning area and the hollow space 120 is known, so that the spatial position of the hollow space 120 can be obtained; further using the known relative position between hollow space 120 and image intensifier 300, the spatial position of image intensifier 300 is obtained. Thus, the spatial position of the image intensifier 300 can be obtained by the spatial coordinates of three or more positioners 140.
