摘要： A method for providing X-ray image data signals corresponding to a selected portion of a two-dimensional image at an enhanced image resolution. During selective exposure of an X-ray receptor to X-ray radiation corresponding to the subject image, image pixel data corresponding to the region of interest (used pixels) are read out with normal pixel data pixel discharge times and at the normal pixel data rate, while image pixel data corresponding to the region not of interest (unused pixels) are read out also with normal pixel data pixel discharge times and at either the normal pixel data rate or an increased pixel data rate. During such pixel data readout intervals, the X-ray radiation exposure can be continuous or selectively pulsed.

摘要： An image sensor having a two-dimensional array of pixel sensors [201], a layer of scintillation material[206], and a controller[202] is disclosed. The layer of scintillation material is adjacent to the two-dimensional array, the scintillation material emits light in response to x-rays impinging thereon. The pixel sensors detect this light. The controller reads out data stored in the two-dimensional array of pixel sensors and forms an image therefrom. The controller corrects the data for errors resulting from x-rays that generate electrons that are stored in the pixel sensors [41] in the process of forming the image. In one aspect of the invention, the controller forms the image by causing the two-dimensional array to form a plurality of frames, each frame includes a measurement of a charge stored on each photodiode[46] during a preceding time period. The controller selectively combines data from the frames to form the image.

摘要： In a system and method for displaying properties on an object (10), an imager (20) is configured to capture an image of an object of interest and generate image data from the captured image, wherein the image data comprise information of the object of interest that cannot be detected by the naked eye, and an image processing unit (40) transforms the imaged data into a viewable format. An image projector (30) displays an image in accordance with the image data transformed by the image processing unit onto the object of interest.

摘要： A self-contained digital imaging array (46) fits in a bucky carrier (26) mounted under the table (4) or other support surface of an x-ray system, permitting conventional film-based analog image capture systems of the prior art to be upgraded to full electronic capability for capturing diagnostic images in digital format, integrating those images with patient demographics, test reports, lab results and other information, and archiving and displaying that information on monitors or hard copy prints. The system of the subject invention permits conversion of the historic film-based analog systems to electronic, fully integrated systems at a fraction of the costs of full replacement systems now available in the marketplace.

摘要： An X-ray imaging system comprising an X-ray image sensor and an image capture controller (30) is provided. The X-ray image sensor includes a sensor array comprising a plurality of CMOS active column sensors (31). The image capture controller (30) communicates with the X-ray image sensor to read out pixel values from selected ones of the CMOS active column sensor elements (31). The image capture controller may randomly select reference pixels from the plurality of CMOS active column sensor elements, and compare a signal of the reference pixels to a predetermined level to determine a start of X-ray exposure. The image capture controller (30) also may randomly select second reference pixels from the plurality of CMOS active column sensor elements (31), and monitor the second reference pixels to determine an end of X-ray exposure. The X-ray imaging system also may include a wireless interface for coupling the X-ray image sensor to the image capture controller. The X-ray imaging system may be used as a dental X-ray imaging system. An intraoral X-ray image sensor comprising a scintillator that converts an X-ray energy image into a visible-light image and a sensor array including a plurality of CMOS active column sensors, which converts the visible-light image into an electrical signal, also may be provided.
