The application of digital radiography has not been used widely in veterinary medicine. This paper gives an overview of the possibilities in post processing of digital radiographs for imaging a nasal fracture on a right lateral skull radiograph of a two years old German Shepherd. The following algorithms of the digital ADC (Agfa Diagnostic Center)--system were used: edge-contrast, latitude reduction, noise reduction, window-levelling and MUSI-contrast (MUlti Scale Image Contrast). MUSI-contrast is a recently developed algorithm by Agfa, which improves the recognition of fine details in all scales. These parameters will be explained individually and the use is demonstrated with the skull radiographs. It shows that only a coordinate parameter setting will lead to an optimal image. The option of filtering diagnostic information in using digital post processing represents a clear step forward and reduces the number of repeat shots.
数字放射成像在兽医医学中的应用尚未得到广泛应用。本文概述了数字X线片后处理在对一只两岁德国牧羊犬右侧颅骨X线片上的鼻骨骨折进行成像方面的可能性。使用了数字ADC（爱克发诊断中心）系统的以下算法：边缘对比度、宽容度降低、降噪、窗宽窗位调整和MUSI对比度（多尺度图像对比度）。MUSI对比度是爱克发最近开发的一种算法，它能提高对所有尺度上细微细节的识别能力。将分别解释这些参数，并通过颅骨X线片展示其用法。结果表明，仅通过坐标参数设置就能获得最佳图像。利用数字后处理来筛选诊断信息这一选择代表了明显的进步，并减少了重复拍摄的次数。
