Digital CR of head and neck overcomes the disadvantage of regular X-ray radiography
which can not reveal bone and soft tissue position deficiency in one exposing
and reduces the Xray radiation dose. Meanwhile
various factors cause the decline of image quality
and images must be enhanced in order to meet demands of doctor's clinical diagnosis. The general enhancement algorithms don't consider body's structure differences and density characteristics. A new adaptive CR enhancement algorithm was proposed in this article
and head and neck CR images were processed with this method and compared with linear unsharp masking method. The experiment proves that the details of CR image enhanced were abundant and enhanced CR image had good visual effect
SNR was high
as well as detail variance /background variance (DV/BV) indicating that this algorithm is suitable for head and neck CR medical images. (2012) Trans Tech Publications

This paper introduces a new imaging method for X-ray coherent scatter based on a new medical digital radiography device. An experimental equipment was set up and the scatter images obtained with it. The scatter images are made of some circles with the same center. With image processing
the energy distribution curve extracted from coherent scatter images. The experiment results show that this method is reasonable and feasible. The study will have wide foreground of application. 2011 IEEE.
