1. A method of determining the presence of lead markers in an X-ray image comprising the steps of:
providing an X-ray system comprising:
an X-ray source; and
an X-ray detector positionable in alignment with the X-ray ray source; and
a processing unit operably connected to the X-ray source and the X-ray detector to produce X-ray images from data transmitted from the X-ray detector, wherein the processing unit includes a lead marker detection system configured to detect representations of physical lead markers in the X-ray images; and
applying the lead marker detection system to the X-ray images,
wherein the representation of the physical lead marker is a representation of a patient position lead marker or a representation of an expiration lead marker.
