Abstract: A radiation imaging device includes plural individual detectors defining an irregular rectangular active area responsive to x-rays and with different widths along a length of the active area. The individual detectors may be of different rectangular shapes and mounted on a motherboard. The motherboard may be formed of a first module mounting a first of two individual detectors and a second module detachable connected to the first module and mounting a second of two individual detectors.

Abstract: An extra-oral digital panoramic dental x-ray imaging system for multi-layer panoramic and transverse X-ray imaging providing with an X-ray source and a digital imaging device providing real time frame mode output and autofocusing. The X-ray source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images.

Abstract: A multi-functional dental extra-oral x-ray imaging system comprises a conventional x-ray source and manipulator to control the movement of the x-ray source by translating and rotating, a real time multiple frame producing x-ray imaging device and at least two different exposure profile programs, whereas one of such profiles produces a standard panoramic image and a second of such profiles produces an angled or transverse slice to a the panoramic image. A third exposure profile program produces a substantially linear projection of the human skull by combining two linear projections, one for the right and one for the left part of the head. The sensor is a linear direct conversion operating preferably in the frame mode and producing more than 100 fps.

Abstract: An extra-oral digital panoramic dental x-ray imaging system is disclosed for multi-layer panoramic and transverse X-ray imaging. The system includes an X-ray source and a digital imaging device capable of “real time” frame mode output. The source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images. For “real time” imaging, the frames memory is a fast data storage system such as RAM. The processing unit executes the reconstruction algorithms, allowing the system to selectively generate dental panoramic X-ray images, dental transverse x-ray images and dental tomosynthetic 3D images.

Abstract: A calibrated real-time, high energy X-ray imaging system is disclosed which incorporates a direct radiation conversion, X-ray imaging camera and a high speed image processing module. The high energy imaging camera utilizes a Cd—Te or a Cd—Zn—Te direct conversion detector substrate. The image processor includes a software driven calibration module that uses an algorithm to analyze time dependent raw digital pixel data to provide a time related series of correction factors for each pixel in an image frame. Additionally, the image processor includes a high speed image frame processing module capable of generating image frames at frame readout rates of greater than ten frames per second to over 100 frames per second. The image processor can provide normalized image frames in real-time or can accumulate static frame data for substantially very long periods of time without the typical concomitant degradation of the signal-to-noise ratio.
