Abstract
Systems and methods are presented herein for generating an X-ray image where the X-ray image generator has no electrical connection with an X-ray source that generates the X-rays. In an exemplary embodiment a gamma detector is positioned behind an x-ray permeable mirror within an X-ray capture device. When the gamma ray detector senses gamma radiation over a threshold level, a camera, positioned outside of the X-ray path, begins capturing an image of the X-ray. The image is then discarded if an X-ray image profile is not then detected by the gamma detector within a period of time. Such an X-ray image profile may be detected if two or more X-ray pulses with similar intensity and duration are detected within a set period of time. If an X-ray image profile is detected, then the camera continues recording the X-ray image for a predetermined time.
