摘要： A method and system for pre-processing a radiation image containing a clinical region of interest and a non-clinical region. The method includes forming a border proximate the clinical region and performing image filtering to filter the clinical region and the border. The non-clinical region may be collimated, and at least a portion of the collimated region may be replaced with values based on pixel values within the region of interest. The system includes obtaining a radiation image having clinical and non-clinical regions, apparatus identifying the non-clinical region, a multi-resolution pre-processing subsystem removing the non clinical region to form an intermediate image and then adding a border to the intermediate image, and a multi-resolution imaging subsystem performing multi-resolution processing of the clinical region and border. Assigned border pixels values may be based on, equal to, or mirror associated or adjacent clinical region pixel values.

摘要： A method for converting a digital image to an analog-simulative film-like digital image is described wherein input pixel values (designated X) from the original digital image are converted to film-like output values (designated Y) wherein Y=AXp+B. The input values X, which range from Xmin to Xmax, are divided into consecutive intervals wherein different values of A, p, and B are applied for each interval. Most preferably, three intervals are defined so as to correspond to low, medium, and high light/radiation response intervals on film. In a low light/radiation region wherein X X2, p is generally chosen to be less than 1 to provide range compression. In the intermediate medium light/radiation region, p is preferably chosen to be approximately 1 to provide a response which is linear with respect to the input, but A is preferably chosen to be greater than 1 to provide range expansion. An image formed in accordance with the resulting output values Y provides an exceedingly good representation of a filmed radiographic image, and may be printed on translucent film for use and analysis in the same manner as a filmed radiographic image produced by analog methods. Additionally, the output values Y can be made to even more accurately mimic the response of film if the aforementioned conversion is expanded in accordance with Y = ∑ i = 1 M ⁢ ⁢ A i ⁢ X p i + B i wherein M is an integer value greater than 1.
摘要翻译：描述了将数字图像转换成模拟模拟胶片数字图像的方法，其中从原始数字图像输入的像素值（指定为X）被转换为其中Y = AXp + B的胶片状输出值（指定为Y）。从Xmin到Xmax的输入值X被划分成连续的间隔，其中对于每个间隔应用不同的A，P和B值。最优选地，三个间隔被定义为对应于薄膜上的低，中和高光/辐射响应间隔。在其中X X2的高光/辐射区域中，通常选择p小于1以提供范围压缩。在中间介质光/辐射区域中，p优选地选择为大约1以提供相对于输入线性的响应，但是优选地选择A大于1以提供范围扩展。根据所得到的输出值Y形成的图像提供了拍摄的放射线照相图像的非常好的表示，并且可以以与通过模拟方法产生的成像放射线图像相同的方式打印在半透膜上以供使用和分析。此外，如果上述转换根据M是大于1的整数值而扩展，则可以使输出值Y更准确地模拟电影的响应。
