摘要： A method and apparatus for displaying an image generated by at least one detector of an imaging unit are disclosed herein. The method includes creating a pixel map identifying locations of bad pixels in an array of pixels in the image detected by the at least one detector, linking the pixel map to the image, and providing for selective display of the pixel map. Bad pixels behave from a group including pixels which do not respond electrically and pixels which are statistically different from surrounding pixels in the array of pixels. The apparatus includes an imaging unit for generating x-rays which pass through a body of interest, at least one detector unit for detecting the x-rays, and a processing unit for identifying bad pixels within the detected image.

摘要： Systems and methods are provided for managing power consumption of a medical imaging detector by the use of triggering signals, environmental condition data, and/or determination of a variable time interval triggering event that is unique for each power consumption state. Systems and methods are provided for managing power and temperature of a device, after receiving a request for a function to be performed by the device determining an “on” trigger component, an “off” trigger component, associated circuits for performing the received function, providing power to the associated circuits upon the occurrence of the “on” trigger component, and removing power to the associated circuits upon the occurrence of the “off” trigger component. Further, an instruction is described for determining and displaying a variable time interval that is indicative of a time to change from one state to a desired state.

摘要： A method and system of aligning an x-ray detector and x-ray tube for data acquisition are presented. The x-ray detector and x-ray tube are equipped with transmitters and receivers designed to provide feedback relating to the orientation, spacing, and general position thereof. In this regard, a user can effectively and efficiently position the x-ray tube and x-ray detector relative to one another for data acquisition.

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.
