Abstract
continuous improvement in image quality produced by CT scanning has occurred since 1972 when the resolution element of the new EMI scanner was 3.0 X 3.0 X 12 mm. We are now working with a fourth generation machine with a resolution element of 0.75 X 0.75 X 2.0 mm. This hundred fold improvement in spatial resolution has had important clinical impact in analyzing diseases of the orbit.
摘要
自1972年以来，CT扫描的图像质量不断提高，当时新型EMI扫描仪的分辨率单元为3.0×3.0×12毫米。我们现在使用的是第四代机器，分辨率单元为0.75×0.75×2.0毫米。空间分辨率提高了百倍，这对眼眶疾病的分析产生了重要的临床影响。
