Method and system for computed radiography using a radio frequency identification device

A method for obtaining an X-ray image of a subject on a flexible information carrier plate for computed radiography. A memory is affixed to a surface of the plate, wherein the affixed memory stores information about the plate and is in wireless communication with a computer. A first scan date is stored in the affixed memory. Obtaining the X-ray image uses steps of storing at least a job identifier and a scan status for the plate in the affixed memory; acquiring image data from a scan of the plate following exposure to X-rays, acquiring at least the job identifier from the affixed memory, and associating the acquired image data with the acquired job identifier; incrementing a scan count value and updating the scan status in the affixed memory; erasing image content from the plate; and storing the acquired image data in a second, computer-accessible memory according to the acquired job identifier.

Integrated ophthalmic illumination method and system

An integrated ophthalmic illumination method and system having two integrated light sources, a lamp and an infra-red (IR) diode laser. The lamp light source may be used to produce either monochromatic or color images, as necessary, at high resolution. In a preferred embodiment, color images are provided using an RGBT (red-green-blue-transparent) filter wheel. The filter wheel is divided into four sections or arc sections around the periphery of the wheel. Three of the four partitioned sections are larger and equal sections that comprise the three optical R, G and B filter sections. The fourth section is a transparent, or empty, narrow section that is used for transferring the full original content of the white beam when a monochromatic or chromatic image is desired. The RGBT wheel rotates at a speed of one third of the frame rate of a CCD camera, producing a sequence of definite R, G and B spectral light bursts. These R, G and B illuminated images are later composed by a computer into a ...

Transcleral opthalmic illumination method and system

A method and apparatus for illuminating the interior of the eye through the sclera without any contact to the eye. The apparatus contains a lamp element and optics that focus the light on the eye sclera. One or more fiber optics bundles may be used to convey the light from the light source close to the illuminated eye, ending with condensing optical elements. Alternatively, light could be conveyed by sharing the optics of an imaging system. It is useful for observing or imaging the interior of the eye, the retina, or the choroid. The observation or the imaging of the interior of the eye, the retina, or the choroid by applying the disclosed illumination method can be done in conjunction with any system that includes optics for that purpose, e.g., fundus cameras and ophthalmoscopes, without using those systems' illumination elements.

Illumination method and system for obtaining color images by transcleral ophthalmic illumination

An illumination system for fundus imaging apparatus employing transcleral illumination of the interior of the eye. Color images of the interior of the eye are obtained by illuminating the sclera successively with red, yellow and green light. Those images are then treated as red, green and blue images by a post processing unit, which combines them to give a color image. This is useful for observing or imaging the interior of the eye, the retina, or the choroid. The observation or the imaging of the interior of the eye, the retina, or the choroid by applying the disclosed illumination method can be performed in conjunction with any system that includes optics for that purpose.
