	Analysis model of X-ray coherent scatter images (EI CONFERENCE) 会议论文 OAI收割 3rd International Conference on BioMedical Engineering and Informatics, BMEI 2010, October 16, 2010 - October 18, 2010, Yantai, China 作者: Liu J.; Liu J.; Li Y.; Li Y.; Li Y. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 X-ray coherent scatter imaging with diagnostic equipment is feasible. The energy distribution extracting from image is a way to get information hidden in images. In this paper a new analysis model of x-ray scatter images was presented. With the model some situations of real coherent scatter image affected by noise eccentricity and energy distribution were simulated. The result shows that the clinical x-ray coherent scatter can be simulated well by a Gauss distribution model. And an inner correlation algorithm was discussed to help calculate center approaching the theory center with the model. 2010 IEEE.
	Study on medical X-ray coherent scatter imaging and processing based digital flat detector (EI CONFERENCE) 会议论文 OAI收割 3rd International Conference on BioMedical Engineering and Informatics, BMEI 2010, October 16, 2010 - October 18, 2010, Yantai, China 作者: Li B.; Zhao J.; Li B.; Li B.; Liu J. 收藏 \| 浏览/下载：32/0 \| 提交时间：2013/03/25 It is introduced a novel imaging technique for medical diagnostic X-ray coherent scatter in this paper. A set of experimental equipment for X-ray coherent scatter imaging was set up with X-ray digital flat detector and medical diagnostic X-ray source. According to this equipment the scatter images obtained are made of some circles with the same center. It is vital to calculate the energy template to classify the different samples. It is difficult to separate them using the traditional threshold method due to noise and overlapped shadow. In this paper the image was transformed a binary image by using K-Means algorithm and Mathematical Morphology Methods. The effective region was extracted from the binary image inside the orthogonal energy projection space then to calculate the centroid of rings. Consequently the curve of the energy distribution was built. The experiment results show that our method is reasonable and feasible. The technique will have wide foreground of application .Besides the imaging of human bone content it can be used for various imaging of tissue and organs in biology. 2010 IEEE.

	Medical X-ray coherent scatter images processing based on the MRF model (EI CONFERENCE) 会议论文 OAI收割 ICO20: Biomedical Optics, August 21, 2005 - August 26, 2005, Changchun, China 作者: Liu J.; Liu J.; Liu J. 收藏 \| 浏览/下载：16/0 \| 提交时间：2013/03/25 X-ray coherent scatter imaging is a novel imaging technique. A clinical X-ray coherent scatter imaging equipment based on image processing method is introduced adopting CR and IP plate instead of the diffractometers. The scatter images obtained are made of some circles with the same center. According to our equipment it is vital to calculate the energy template to classify the different samples. However it is difficult to separate them using the traditional threshold method due to noise and overlapped shadow. Markov Random Field (MRF) is employed to segment the scatter image which takes spatial information into account to deal with the noise and overlapped shadow. The experiment results show our method is reasonable and feasible.
