Original Abstract Submitted
The present invention relates to an object detection method and system for an imaging device. At least a part of an object is located in a subject under examination. The object detection method includes: obtaining volumetric image data generated by scanning a region of interest of the subject by the imaging device; converting the volumetric image data into feature projection images, the feature projection images including three orthogonal plane feature projection images; detecting coordinates of the object in each of the three orthogonal plane feature projection images to obtain corresponding projection coordinates of the object in respective coordinate systems of the three orthogonal plane feature projection images; and obtaining global coordinates of the object in a global coordinate system of the imaging device on the basis of the projection coordinates of the object.
