摘要： An imaging system shares control of host memory between a detector framing node and a host processor. The detector framing node is programmable to control generation and reception of image data. Image data is acquired and communicated to host memory independently from control by a host operating system. The detector framing node controls events according to an event instruction sequence and communicates received image data to the host memory through a computer communication bus. Image data is received by the detector framing node from a flat panel detector. Host memory has a first section managed by the host operating system and a second section not managed by the host operating system. Image data is communicated from the detector framing node into the second section of host memory. Event instruction sequences are communicated from the first section of host memory to the detector framing node to control the generation and reception of image data.

摘要： An image detector monitoring system includes a detector framing node and a host computer having at least one host processor and a host memory. The detector framing node acquires image data, buffers the acquired image data, and outputs the image data to the host memory according to a predetermined communication protocol. The host computer executes operations according to a non-real time operating system, and a host memory stores the image data received from the detector framing node. The detector framing node is controlled by executing a plurality of event instructions, which are stored in an event queue. Some event instructions control a radiation generation system, while others control communication with an image detection system or control the detector framing node itself. Each event instruction executed by the detector framing node includes a bit flag indicating whether the event is to be traced by the detector framing node. Traced events are stored as entries in a response log in host memory. Each response log entry includes a time stamp indicating a time of execution of the traced event.

摘要： A detector framing node controls generation of radiation and radioscopic image detection Radioscopic image data is acquired and communicated independently of a host computer operating system. The detector framing node controls events in real time according to an event instruction sequence and receives the image data by way of an image detection interface into a memory unit. The image data is output from the memory unit to host memory of the host computer through a computer communication interface and under the control of a control unit. The detector framing node selects a flat panel detector from a plurality of different flat panel detectors and the image data is selectively reordered according to parameters of the selected flat panel detector before communication to host memory.

摘要： A method, system and apparatus for processing a radiographic image of a scanned object is disclosed. A pixel offset correction is performed in integer format on the radiographic image using saturation arithmetic to produce an image in integer format with any negative corrected values clipped to a value of zero. The resulting pixels are converted to floating point format and the converted pixels are multiplied by a gain factor. Optionally the resulting pixels are recursively averaged with previous results. The resulting pixels are converted to integer format and the converted pixel values are clamped to a maximum value using saturation arithmetic. Non-functional pixel correction is performed in integer format and the resulting pixel values are clamped to a maximum value using saturation arithmetic. An optional processing path replaces the recursive average by a linear average. The resulting pixel values are optionally filtered to enhance features of interest. The resulting pixel value is mapped in integer format to a palette index to establish an output pixel intensity having one of many intensity levels. The optional processing is controlled through the hardware interface of a real-time image controller as images are acquired.

摘要： A method and system of processing raw images for display. First, a processor corrects the raw images with respect to an offset image to generate an offset corrected image. Next, a level of the offset corrected image is adjusted with respect to a gain adjust by employing saturation arithmetic to clip the level of the offset corrected image to generate a gain corrected image. Next, a window of the gain corrected image is adjusted with respect to a reference window to generate an output image. Next, the output image is packed into a register for display.
