20110069816 | APPARATUS FOR REDUCING SCATTERED X-RAY DETECTION AND METHOD OF SAME - A method, system, and apparatus including an x-ray detector unit that includes an anti-scatter grid free of at least one of a top cover and a bottom cover, a flat panel x-ray detector having an x-ray conversion layer, and an integrated anti-scatter grid assembly configured to provide structural support to the anti-scatter grid and to provide mechanical protection to the flat panel x-ray detector. The anti-scatter grid is configured to absorb a plurality of scattered x-rays impinging on the anti-scatter grid while substantially allowing un-scattered x-rays to pass through the anti-scatter grid. The x-ray conversion layer is configured to convert an x-ray into visible light or an electronic signal. The flat panel x-ray detector is fixed relative to the anti-scatter grid such that the anti-scatter grid remains stationary relative to the flat panel x-ray detector during operation of the x-ray detector. | 03-24-2011 |
