摘要: A data management system automatically manages image buffers to produce images for angiography using a first memory portion, a second memory portion and an image data processor. The first memory portion stores first image frame data representing minimum luminance values of individual pixels of a sequence of medical images. The second memory portion stores second image frame data comprising a difference between the minimum luminance values and corresponding maximum luminance values. The image data processor processes data representing an acquired X-ray image frame of a catheterized vessel using a stored frame of maximum or minimum pixel luminance values and the second image frame data to provide an image with enhanced visualization of a catheter in a vessel.

摘要: An error detection system is used by an image processing subsystem for detecting error in processing medical image data by multiple sequential subsystems using an image data processor. The image data processor in the image processing subsystem analyzes data representing a medical image to identify a sequence identifier associated with a subsystem preceding the image processing subsystem of the multiple sequential subsystems and identifies a position of the image relative to other images in an image sequence comprising multiple consecutive images. The image data processor uses the identified sequence identifier to detect an error in response to identifying at least one of, an unreadable sequence identifier and a missing sequence identifier. The image data processor incorporates a sequence identifier, in image data representing an area of the image associated with the image processing subsystem and initiates generation of an alert message in response to a detected error.

摘要: A system automatically detects and reports a hardware and/or software error in an X-ray system. A system automatically detects and identifies failed components of a distributed X-ray imaging system. Multiple different subsystems of an X-ray imaging system individually include, an executable procedure for detecting a failed component in a respective subsystem and a communication interface for initiating generation and communication of a message identifying the failed component and identifying the respective subsystem including the failed component. A repository stores data identifying failed components within the multiple different subsystems in response to the communicated message. An error processor accesses the repository of data and provides composite information enabling a user to identify failed components within an X-ray imaging system.

摘要: A ballast assembly for a fluorescent lighting fixture has a magnetic core, a primary winding and a secondary winding, both windings mounted on a central leg of the core, with a shunt disposed between the windings to prevent a flux generated by the primary winding from coupling with the flux generated by the secondary winding. The ballast further includes a shunt retaining clip disposable between the windings, the clip including a essentially U-shaped wall having a pair of upright portions and a crossover portion, a bottom ledge attached to the crossover portion for accepting the shunt. A spring arm extends between the pair of upright wall portions of the U-shaped wall with the spring arm sized to resiliently engage a top surface of the central core leg. By resiliently engaging the top surface, the clip and the shunt positioned thereon are accurately located relative to the central core thereby assuring long-term stability of the shunt, increasing efficiency and eliminating inconsistencies in magnetic flux concentration from ballast to ballast.
