Reason for unclarity of CR picture

目的：控制CR图像的模糊度，提高CR影像的质量。方法：通过分析CR图像成像过程中引起锐利度下降的各种原因，提出有效控制CR图像清晰度的方法。结果：选用合适的IP极、止确的投照技术和X线照射量等方法，可将照片锐利度的下降限制在最小的允许范围内，获得优质的CR照片影像质量。

Objective To control the ambiguity of the CR image. Methods Effective controlling method is proposed after analyzing all the reasons for sharpness drop in CR image formation process. Results When appropriate IP board is selected and correct projection photography and X-ray bombardment quantity are used, the picture sharpness can be limited within the smallest permission scope drop so as to obtain the high quality of CR picture image.
