Background Identifying gastric heterotopic pancreas and stromal tumors is difficult. Few studies have reported computed tomography (CT) findings for differentiating lesions less than 3 cm in diameter. In this study, we aimed to identify clinical characteristics and CT findings that can differentiate gastric heterotopic pancreatic lesions from stromal tumors less than 3 cm in diameter. Methods A...
X-ray computed tomography (CT) scanning technology has been applied to the detection of internal defects in logs for the purpose of obtaining prior information that can be used to arrive at better log sawing decisions. In addition to the recognition of wood internal defects, computed tomography technology can be applied to wood nondestructive testing. In the paper the range of CT number in different...
Mathematical morphology is the emerging theory and method in digital image processing now. Based on the basic theory and algorithm of mathematical morphology, self-adaptive multi-scale weight morphological operator was advanced and used in the defect identification of wood products X-ray computed tomography image. As can be seen in the experimental analysis, compared with the traditional edge detection...
Multifractal spectrum theory was applied in the edge detection of medical CT image. As shown in the experimental result, the method based on multifractal theory in detecting medical CT image was effective. Multifractal theory is a more local method in detecting edge of image. Thus, a new method based on multifractal spectrum in detecting medical image is provided.
With the increase of wood demand, wood nondestructive testing technology becomes more and more important. Many nondestructive technologies are established on the basis of multi-subject and high technology. Wood nondestructive testing technology is a comprehensive subject. Recently it has achieved fast development. X-ray computed tomography (CT) scanning technology has been applied to the detection...

Wood has long been an important building material. The wide variety in appearance, strength properties and the possibility of different dimensions are some of the reasons why wood is still very attractive for this purpose. Wood nondestructive testing technology is a new and comprehensive subject. In recent years it has achieved fast development. Computed tomography offers great potential for non-destructive...
Wood non-destructive testing technology is a new and comprehensive subject. An approach of image edge detection based on morphology of omnidirectional and multi-scale structuring element is constructed by weighting method of morphological operation. In recent years wood non-destructive testing has achieved fast development. Computed tomography (CT) scanning technology has been applied to the detection...

In this paper, we apply computed tomography (CT) technology for log nondestructive testing and calculate the CT number range of different log tomography slices in statistic method, then the parameters of CT window level and window width in log testing procedure were set. Thus it provides a fast operation procedure in the log nondestructive testing based on CT. Because of the linear relationship between...
