摘要： A method for obtaining a radiographic image, the method executed at least in part on a computer, generates a first exposure and acquires image data from the first exposure as a first component image. A second exposure is generated using one or more parameters that are adjusted according to an image quality characteristic of the acquired image data from the first exposure. Image data is acquired from the second exposure as a second component image. One or more additional exposures are generated and an additional component image acquired with each additional exposure. A composite image is formed by combining image data content from the first and second component images and the one or more additional component images.
摘要翻译：一种用于获得射线照相图像的方法，所述方法至少部分地在计算机上执行，产生第一曝光并且从第一曝光获取图像数据作为第一分量图像。使用根据从第一曝光获得的图像数据的图像质量特性调整的一个或多个参数来生成第二曝光。从第二曝光获取图像数据作为第二分量图像。产生一个或多个附加曝光，并且每次附加曝光获得附加的组件图像。通过组合来自第一和第二分量图像的图像数据内容和一个或多个附加分量图像来形成合成图像。

摘要： A method for automatically modifying the rendering of an image based on an analysis of pixel values within a selected region of interest. The method includes: providing a digital input image of digital pixel values and tone scale look-up table (LUT); creating a default rendered image by applying the tone scale lookup table to the input image; displaying the default rendered image; selecting a region of interest from the input image; computing the histogram of the pixel values within the region of interest; creating a bright light image by remapping the pixel values within the region of interest based on an analysis of the histogram and the tone scale table; wherein the tone scale lookup table has been adjusted by one or more of increasing or decreasing the overall contrast, and of reversing the polarity of the tone scale LUT; and overlaying the bright light image on default rendered image.
摘要翻译：一种用于基于对所选择的感兴趣区域内的像素值的分析来自动修改图像的呈现的方法。该方法包括：提供数字像素值和色阶查找表（LUT）的数字输入图像; 通过将色阶查找表应用于输入图像来创建默认渲染图像; 显示默认渲染图像; 从输入图像中选择感兴趣区域; 计算感兴趣区域内的像素值的直方图; 通过基于直方图和色阶表的分析，重新映射感兴趣区域内的像素值来创建亮光图像; 其中，通过增加或减少整体对比度和使色阶LUT的极性反转的一个或多个来调节色阶查找表; 并将亮光图像叠加在默认渲染图像上。

摘要： A method for defining the shape of a radiation beam that is directed toward a subject and to a free-standing imaging detector detects the position and orientation of the imaging detector relative to a radiation source, then adjusts an aperture that lies in the path of the radiation beam to shape the beam for incidence on a predetermined area of the detector according to the detected imaging detector position. The radiation source is energized to emit the shaped radiation beam and the image data about the subject is acquired from the imaging detector.
