Abstract
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.
