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： In recent years, x-ray imaging, which has been used to diagnose millions of illnesses and injuries, has evolved to use digital imaging instead of photographic film as a recording medium. Digital x-ray systems typically include an x-ray source, an x-ray focusing grid, and an array of light or x-ray detectors. Because of detector imperfections and other system factors, such as x-ray field non-uniformity and grid artifacts, digital x-ray images are often corrected, or compensated, before use. To this end, many digital x-ray systems include numerous application-specific correction maps, which unfortunately require regular maintenance that is not only time-consuming but expensive in terms of system downtime. Accordingly, the inventors devised new methods and systems for correcting application images that require maintenance of fewer correction maps. One exemplary implementation determines grid-only and non-grid correction maps and corrects application images based on a combination of these correction maps. Other aspects of the invention include automatic detection and correction of grid images in application images and computer-readable mediums which store software for computing and applying grid-only and non-grid correction maps.

摘要： In an X-ray imaging system, an arrangement is provided for readily aligning the system detector with the X-ray beam field, i.e., the projection of the X-ray beam into the plane of the detector. The arrangement is adapted for correcting or compensating for distortion which results from X-ray beam angulation, wherein the beam is projected toward the detector plane at an angle of less than 90°. Initially, the system X-ray tube is positioned to project the X-ray beam at a given beam direction angle &phgr;. A beam width angle &ggr;1 is then computed, from the given angle &phgr; and from specified values of the source-to-image distance and the length of the projected beam field. Thereupon, an offset value is determined from &ggr;1, &phgr; and the source-to-image distance to locate the geometric center of the beam field, and the center of the detector is aligned therewith.

摘要： A computer implemented method, apparatus, and computer program product for processing aircraft software parts. A crate containing an aircraft software part is received from a source. Signatures are validated for the crate and the aircraft software part. If the signatures are valid, the crate is unpacked. The contents of the incoming crate are displayed. The aircraft software part is unpacked. Responsive to a request to upload the stored part to a library in the aircraft software part management apparatus, a determination is made as to whether the stored part meets a policy. If the stored part meets the policy, the part is signed. The signed part is placed in a crate and is signed to form a signed crate wherein signatures for the signed aircraft software part and the signed crate are different from the set of signatures in the incoming crate. The signed crate is sent to the library.

In some embodiments, the apparatus and method develops one or more offset maps, acquired during system idle, for the imaging system at a plurality of exposure windows. In some embodiments, exposure parameters acquired for the imaging system before image acquisition are used to select an offset map to subtract from subsequent X-ray images. In some further embodiments, executable instructions are disclosed for directing a processor to compile one or more offset map and exposure parameters to subtract based on a selected offset map noise elements from X-ray images and thereby minimizing the time between image acquisition and display of processed images.
