	Application of adaptive enhancement means in head and neck CR image (EI CONFERENCE) 会议论文 OAI收割 2012 3rd International Conference on Information Technology for Manufacturing Systems, ITMS 2012, September 8, 2012 - September 9, 2012, Qingdao, China Zhang M.-H.; Zhang Y.-Y. 收藏 \| 浏览/下载：35/0 \| 提交时间：2013/03/25 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.

	Experiment of coherent scatter imaging based digital radiography device (EI CONFERENCE) 会议论文 OAI收割 2011 IEEE International Conference on Computer Science and Automation Engineering, CSAE 2011, June 10, 2011 - June 12, 2011, Shanghai, China 作者: Li B.; Wang K.; Liu J.; Liu J.; Liu J. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 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.
