摘要
数字化摄影(DR)平板探测器受到环境温度、平板探测器坏点等因素影响,所得到DR影像会出现伪影,或者影像的分辨率、空间分辨率、对比度、均一性变差或降低。通过对DR平板探测器定期校准,可以消除因为平板探测器因素对DR影像质量的影响。
DR flat-panel detector is affected by factors of environmental temperature and bad pixels, etc, thus, artifacts would appear in DR images, and the image resolution, spatial resolution, contrast and homogeneity variation would be lower under the influence of these factors. Periodic calibration of the flat-panel detector of DK can etiminate the influence of these factors.
