Digitale Bilddiagn. 1988 Dec;8(4):147-51.
34 patients with skeletal alterations mostly in the periphery were investigated by digital image intensifier radiography (DIIR). A high resolution image-intensifier system (1024 x 1024 matrix, 40 cm, 28 cm, 14 cm image intensifier, maximal spatial resolution: 3.6 lp/mm) was available. The image quality was diagnostic sufficient in 76% using DIIR. A good or very good image quality of fine-structures was obtained only in 41%. The quality deficits in comparison to conventional radiograms were particularly obvious in investigation of the phalangeals. Logarithmic amplification and software upgrading lead after these first clinical investigations to a better image quality.
34例主要为外周骨骼改变的患者接受了数字影像增强X线摄影(DIIR)检查。使用了高分辨率影像增强系统(1024×1024矩阵,影像增强器尺寸为40cm、28cm、14cm,最大空间分辨率:3.6 lp/mm)。采用DIIR时,76%的图像质量具有诊断价值。仅41%的图像获得了关于精细结构的良好或非常好的图像质量。与传统X线片相比,在指骨检查中质量缺陷尤为明显。经过这些首次临床研究,对数放大和软件升级带来了更好的图像质量。
