An X-ray image detector has been disclosed comprising X-ray sensitive storage means for storing an X-ray image, which storage means emit image-wise modulated light when being stimulated, and a two-dimensional position sensitive gaseous photon detector. An image stored by the detector is read by line-wise stimulation of the X-ray sensitive storage means followed by measurement of the charges generated by the gaseous photon detector.

X-ray image detector and read out apparatus

A method and apparatus are disclosed for enhancing the contrast of a digital image by

Method and apparatus for contrast enhancement

In the digital processing of radiographic images, interpretation of the image is aided by converting the pixels of an original radiographic image into electrical signals generally corresponding to the densities of the individual pixels and adjusting the electrical signals for the pixels constituting a diagnostically non-relevant image zone, selectively of the pixels constituting a diagnostically relevant image zone, as determined by observation of a visualization of the original radiographic images, e.g. by a radiologist viewing such image on the screen of a viewing monitor, to a density level such that when the electrical signals including the adjusted signals are visualized into an image for interpretation, the pixels of the diagnostically non-relevant zone are effectively masked out and light from the non-relevant zone is prevented from interfering with viewing of the relevant zone. Various predetermined configurations, e.g. a rectangle, circle or polygon, can be selected for the relevant zone for generation by identifying a few selected points on the original. image being viewed, e.g., opposite corner points for a rectangular, a center point and perimeter point for a circle, etc. The visualized image with the blanked out non-relevant regions can be recorded electronically as a soft copy or photographically as a hard copy on a photographic recording medium. Border regions around the image can be made of maximum density, e.g. black, while the density of the non-relevant zone is adjusted to a lesser but still masking density.

Processing method in radiographic image recording systems

Method and apparatus for displaying images obtained by reading out stimulable phosphor screens wherein radiation images are stored. A mosaic type image is composed by means of a plurality of read-out images and said mosaic type image is displayed on a preview monitor or on one of a plurality of preview monitors.

Radiation image displaying method and apparatus

A cassette for an x-ray film coated with a stimulable phosphor layer is formed so that a cassette memory which carries storable, recordable, readable and erasable data is rigidly attached to the cassette at the positioned spaced a predetermined distance from a given cassette corner. This position is the same for all cassettes of the same type and different formats.

X-ray cassette for sheet x-ray receiving material and method of

Method and apparatus for improving the perceptibility of details on a hard-copy of a color image and for matching the color of a displayed image and a color hard-copy of the same image. In addition to the recording of the color information, at least one white light exposure modulated by the information of at least one color separation record is performed.
