摘要： The present technique involves remote processing and comparison of medical diagnostic images obtained over a period of time. A remote processing system is provided to match and subtract the medical diagnostic images, which may be received from users and gathered from remote image storage systems. Users are able to interact with the remote processing system through uniform interfaces, which may be disposed at medical institutions to provide platform independent interaction with, and remote processing by, the remote processing system. The technique also uses compression routines to facilitate network transfers of images between the uniform interface and the remote processing system.

摘要： A method and system for of defining, or identifying, regions of interest for exposure management in a digital x-ray imaging system, and especially in the case of multiple consecutive image acquisitions. According to the most basic embodiment of the present invention, simple geometric shapes arranged in a matrix configuration are used to aid an operator in identifying a region of interest for a diagnostic x-ray image. Each region of interest is selectable from a low-dose preshot image and may be corrected, or processed, in order to enhance the results of a subsequent diagnostic image. The processing of the preshot image allows the system to automatically make predictions for the diagnostic image exposure requirements, thereby avoiding unnecessary multiple images.

摘要： A method includes obtaining a first image of a subject at a first position, changing a position between the detector and the subject, obtaining a second image, and pasting the first and images to obtain a composite image. The first image and the second image may have an amount of overlap equal to no more than about 30 percent of a field of view of the detector in a direction of movement between the first image and the second image, and, according to some embodiments, may have an overlap of about 4 percent to about 16 percent. This may, in some embodiments, amount to an amount of overlap of about 1.5 cm to about 6.5 or 12 cm. In some embodiments, the span of overlap of the images is at least about 30 cm. The geometry of the images may be used to help paste the images together appropriately.

摘要： A device for use in image pasting is described. The device includes a digital x-ray detector capable of automatic digital imaging without the use of an image intensifier; the detector preferably being a flat-panel detector. Additionally, an image pasting system using a solid-state detector is described. The system can connect the detected images to a display via a network (such as a WAN, a LAN, or the internet). Further, an image geometry measurement device for use in pasting x-ray images is disclosed. The geometry measurement device helps determine the relative position of two images to be used in image pasting. This information can be used alone, or in connection with an image pasting algorithm. Still further, methods of forming composite images are disclosed using a flat-panel detector and using the geometry of the images. The disclosed devices and systems can be integrated with other digital image pasting technology.

摘要： A method and system of electronically detecting and measuring gravitational loads placed on an x-ray detector is disclosed. An x-ray detector incorporates an accelerometer that detects and provides an output as to the extent of gravitational loads or forces placed thereon. The accelerometer may also time and/or date stamp each recorded event such that a technician may determine when the x-ray detector was subjected to a particular load. A microcontroller/microprocessor may also compare a current reading of the accelerometer to a threshold and, based on the comparison, provide an audio or visual indication that the x-ray detector has been subjected to a potentially damaging gravitational load.

摘要： A method, system, and apparatus including an x-ray detector unit that includes an anti-scatter grid free of at least one of a top cover and a bottom cover, a flat panel x-ray detector having an x-ray conversion layer, and an integrated anti-scatter grid assembly configured to provide structural support to the anti-scatter grid and to provide mechanical protection to the flat panel x-ray detector. The anti-scatter grid is configured to absorb a plurality of scattered x-rays impinging on the anti-scatter grid while substantially allowing un-scattered x-rays to pass through the anti-scatter grid. The x-ray conversion layer is configured to convert an x-ray into visible light or an electronic signal. The flat panel x-ray detector is fixed relative to the anti-scatter grid such that the anti-scatter grid remains stationary relative to the flat panel x-ray detector during operation of the x-ray detector.

摘要： In an X-ray imaging system comprising an X-ray source, a digital X-ray detector and a display device, an arrangement is provided for setting or establishing the dynamic range of the image at the display device. The detector is operated to provide a set of count values representing X-ray image data acquired by the detector from an object of imaging, and a set of standardized values, such as optical density values, is derived from the count values. The optical density values collectively define a range of optical density values, and the dynamic range of the display device is mapped thereto. The display device is enabled to present an image of the object which appears similar to or substantially the same as an image of the object presented by, for example, a specified analog X-ray film.
