Abstract: A system and method for digital x-ray imaging may correct distortion in a digital image by determining the cell size of a grid. A rotational correction may be applied to the cell to correct for distortion that might result from improper alignment between an imaging sensor used to capture the image and the image itself. Stretch factors for the pixels are calculated and applied to the cells of the grid to provide cells of consistent size. The calculated stretch factors may be applied to subsequent images to provide an efficient method for optical distortion correction.

Abstract: A system and method for high resolution digital x-ray imaging which utilizes a single imaging sensor is disclosed. In the preferred embodiment, the system utilizes a single imaging sensor and includes one or more redirecting elements to redirect a predetermined portion of light from an imaging screen onto the imaging sensor.

Abstract: A system and method for high resolution digital x-ray imaging which utilizes multiple imaging sensors is disclosed. In the preferred embodiment, the system includes multiple imaging sensors with overlapping fields of view. The imaging sensors are preferably interfaced with a general purpose computer capable of seamlessly combining the multiple images captured by the multiple imaging sensors.

Abstract: A system and method for digital x-ray imaging which utilizes optical path folding by redirecting the image more than once before providing it to an imaging sensor is disclosed. In the preferred embodiment, multiple redirection or folding of light is achieved by multiple redirecting elements. An imaging sensor is preferably used to capture the image from the multiple redirecting elements. Such an imaging sensor may comprise a photosensitive plate and a lens assembly.

Abstract: The inventive mechanism uses the output of a visible light sensor to provide accurate signal detecting and noise filtering. When the mechanism detects light for a sufficient duration and intensity in the right wavelength, it generates a trigger signal that activates a camera to record an image. Any noise in the light sensor signal is filtered out or ignored by the mechanism. The mechanism measures the light sensor signal over time, and for a signal to be an accurate signal, each measurement needs to be higher in voltage than the preceding measurement, otherwise the signal is rejected as noise.
