Method for acquiring standard axial view of vertebral pedicle

The invention relates to the field of medicine, in particular to a method for acquiring a standard axial view of the vertebral pedicle. The method comprises the following steps that S1, a pedicle screw implanting path is planned according to preoperative CT data; S2, an X-ray diagram of the vertebral pedicle of a target object is shot through a C arm X-ray machine in a normal view; S3, the rotating direction and the corresponding rotating angle of a C arm rotating to the standard axial view of the vertebral pedicle are calculated according to the planned pedicle screw implanting path and the current X-ray diagram; S4, the pose of the C arm is adjusted according to the rotating direction and the corresponding rotating angle. Therefore, the needed further rotating direction and the corresponding rotating angle of the C arm rotating to be in the standard axial view of the vertebral pedicle are calculated by combining the pre-planned pedicle screw implanting path and the current C arm pose reflected by the X-ray diagram, then the C arm is rotated according to the rotating direction and the corresponding rotating angle, high goal orientedness is achieved, and the standard axial view of the vertebral pedicle can be fast obtained.
