摘要： A discrete pixel image is enhanced to bring out particular features of interest such as edges. The enhancement includes decomposition of the original processed image data, enhancement by application of gain images to the decomposed images, and reconstruction of the enhanced image. The decomposition proceeds through a series of low-pass filters to arrive at decomposed images of progressively lower spatial frequencies. These decomposed images are then multiplied by gain images during the enhancement phase. Gain images for at least the higher spatial frequency level images are derived from lower spatial frequency level images. These spatial frequency-based gain images may be based upon operator inputs, including a spatial sensitivity function and an edge enhancement value. Lower spatial frequency level images may be processed by application of predetermined gain values. The reconstruction sequence recombines the decomposed images after application of the gains to arrive at an enhanced image of the same dimensions as the original image.
摘要翻译：离散像素图像被增强以产生诸如边缘的特定的感兴趣的特征。该增强包括原始处理的图像数据的分解，通过对分解的图像应用增益图像的增强以及增强图像的重建。分解通过一系列低通滤波器进行，以得到逐渐降低的空间频率的分解图像。然后在增强阶段将这些分解图像乘以增益图像。至少较高的空间频率水平图像的增益图像从较低的空间频率水平图像导出。这些基于空间频率的增益图像可以基于操作者输入，包括空间灵敏度函数和边缘增强值。可以通过应用预定增益值来处理较低空间频率电平图像。重建序列在施加增益之后重组分解的图像，以获得与原始图像相同尺寸的增强图像。

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 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： 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： 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.

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.
