摘要
采用数字图像增强x线摄影(DIIR)对34例以外周为主的骨骼改变患者进行了研究。高分辨率图像增强系统(1024 × 1024矩阵,40 cm, 28 cm, 14 cm图像增强器,最大空间分辨率:3.6 lp/mm)。使用DIIR, 76%的图像质量诊断是足够的。精细结构图像质量良好或非常好的仅占41%。与常规x线片相比,质量缺陷在调查指骨时尤为明显。在这些首次临床研究之后,对数放大和软件升级导致更好的图像质量。
[Digital radiographic image enhancement in bone diagnosis--initial clinical results].
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.
