The key point in removing foreign matters in the body is whether the body surface positioning is accurate or not, and the key point is that the foreign matters can be successfully removed or not, and the foreign matters are related to the operation range, the wound size and the recovery quality of wounded after operation.
The body surface of the foreign body is positioned by using a common X-ray diagnostic machine, and the body surface position is usually obtained by using an external label. Because the beams of the common X-ray diagnostic machine are distributed in a conical shape, the X-rays are perpendicular to the skin horizontal plane only at the beam center point, besides the in-vivo foreign matters are just positioned at the conical beam center point, the accurate body surface projection positions can be obtained through a body surface external labeling method, the accurate body surface projection positions can not be obtained through the body surface external labeling method at other positions, and the further the in-vivo foreign matters are far from the skin, the inaccuracy is further caused. In order to accurately position the body surface, the body position of the patient needs to be repeatedly adjusted so that the foreign body in the body coincides with the central line of the cone beam, and if the depth of the foreign body needs to be acquired, the patient needs to be overturned to shoot a side position image. For this reason, two mutually perpendicular metal mesh positioning methods are adopted, and although the positioning efficiency of the foreign body in the body is improved in a certain procedure, the positioning result is still unsatisfactory due to the inherent characteristics of the cone beam.
