The aim of the study was to optimize the postprocessing of digital luminescence radiographs of interstitial infiltrates of the lung.
Ninety-seven patients with established diseases of the lung parenchyma were examined: 514 pathological details were investigated, using a 200-speed screen-film system and a storage phosphor plate. In digital postprocessing, the size of the filter kernel (S) varied between S 5 and S 70. Based upon 32896 individual evaluations, the image quality was evaluated in multifactorial variance analyses.
The digital standards were significantly inferior to the tested screen-film system. The large filter kernel S 70 and the small filter kernels S 5 and S 10, as well as an algorithm for edge enhancement, showed selective advantages in the depiction of nodular or small linear structures. For micronodular and linear structures, kernel sizes of S 20 and S 40 produced equally good results (p > 0.05).
Whenever optimized postprocessing is involved, storage phosphor radiography is equal to a modern screen-film system and can be substituted for the latter without any loss of image quality; this is especially valid for the imaging of interstitial infiltrates of the lung.
本研究的目的是优化肺部间质浸润数字发光射线照片的后处理。
对97例确诊为肺实质疾病的患者进行检查：使用200速屏片系统和存储磷光板对514个病理细节进行研究。在数字后处理中，滤波核大小（S）在S 5至S 70之间变化。基于32896次个体评估，在多因素方差分析中评估图像质量。
数字标准明显不如测试的屏片系统。大滤波核S 70以及小滤波核S 5和S 10，以及边缘增强算法，在显示结节状或小线性结构方面具有选择性优势。对于微结节和线性结构，S 20和S 40的核大小产生了同样好的结果（p>0.05）。
只要涉及优化后处理，存储磷光体射线照相术等同于现代屏片系统，并且可以替代后者而不会损失任何图像质量；这对于肺部间质浸润的成像尤其有效。
