Remote triggered X-ray image capture device with gamma ray detector
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.
1. A method of generating an X-ray image, comprising:
converting at least some X-ray photons generated from an X-ray source to light photons;
triggering a gamma ray sensor when the gamma ray sensor detects X-ray photons in an amount greater than a threshold amount;
using a first mirror to reflect the light path such that substantially all of the light photons are reflected towards a ccd camera, the ccd camera beginning recording the light substantially when the gamma ray sensor is triggered;
the ccd camera continuing to record the light for a predetermined time to produce an X-ray image; and
recording the X-ray image to a storage medium only if the gamma ray sensor senses at least two X-ray pulses within a predetermined time.
2. The method of claim 1 wherein the ccd camera records the light to create the X-ray image for a predetermined time after the X-ray source has ceased generating X-rays.
3. The method of claim 1 wherein the ccd camera records the light for 0.5 seconds.
4. The method of claim 1 wherein the ccd camera destroys the X-ray image if the gamma ray sensor does not sense at least two pulses within the predetermined time.
