Abstract
Multiple x-ray images are encoded onto a single storage phosphor screen detector for later scanning, processing, and viewing. The x-ray images are encoded using spatial frequency multiplexing onto high frequency carriers. The encoding process relies only on light with no mechanical motion. The light erases selected portions of the image data but leaves sufficient information to reconstruct the original images. The reconstruction process relies on conventional sampling theory with the additional step of solving a system of equations for the individual x-ray image information.
