Pulmonary blood circulation disorder lesions macro image analysis


End. Calibration unit, you can request samples based on the experimental measurements. Left, right lung separately, clear airways and hilar fat group at the testis {, each Ba Ba lung hilum to the lung from the outer edge for four parallel longitudinal section were measured in each section of the gray area. Lung surface in the same plane, can not focus, so the unexpected can see the surface of lesions. 『Sub-winged gray-level natural process can be directly called O ~ 64 level (pitch-1), histogram display and print well on the value of each level of phase tangled (as opposed to orderly and proportional to the area.) The purpose can be based on the experimental O ~ 64 arbitrary set number of within-grade-level, gray level spacing may be equal. 3, macroscopic and microscopic lung lesions observed in the contrast: will have made the determination of lung biopsy specimens, the macro different color, different gray values ​​measured in the lung tissue under light microscope observation was further clarify the different gray level of the lesion basis. 4, the determination of score of different diseases: According to the tissue lesions of different gray-scale basis,[link widoczny dla zalogowanych], considering its pathophysiologic effects on the gray level were given 0,1,3, and 4, the weight of a section of the gray The area percentage weight of the product and the corresponding score for that section, section scores of forty and is the final score of the side of the lung. The higher the score, the more severe lesions, and vice versa. Results and discussion First, the gray level of different lung diseases of blood circulation disorders are hyperemia, edema and bleeding,[link widoczny dla zalogowanych], staggered three mixing occurs individually or in the lungs showed a different range of macro, different shapes of different color areas. Impact injuries to the lungs burn-blast combined injury to fully reflect these different Xuexun barrier lesions. Fresh lung samples for the color red, for different diseases and there is bleeding deep red to dark red shades; congestive edema of the red lighter while not significant {simply red, but many also have congestion and (or) bleeding lung specimens were fixed , color from red to black, brown, but also because of the severity of which has depth. The main factors determine the color depth of the extent of bleeding. This may be obtained by image analysis of gray value Each specimen were measured in different parts of a color of gray value, to obtain large amounts of data. In reality, you need to disease and injury as reflected in the grading, which will be divided into a number of the gray value of gray level 4. This is summarized on the basis of detailed quantitative general,[link widoczny dla zalogowanych], different from the usual rough distinction between the several levels (such as mild, moderate, severe, severe stick), better reflect the disease (and injury) to quantify the exact extent of the true comprehensive macro, microscopy and measured gray values ​​(level) the relationship between the attached table and charts. Schedule of lung macro-, microscopic examination and comparison of gray black gray cans decorated with light brown to gray brown or almost 100 10050 ~ 85loYa ~ 50 less normal or nearly normal oH? 526 ~ 3637 ~ 5354 ~ 64 Second, on the different gray level the weight of the impact of different lesions on the body is different and therefore can not be measured simply the sum of the gray value to indicate the severity of disease. Consider the lesions (especially bleeding) in the pathophysiology of effects, given the different gray-scale factors'. is to determine 0 to 25 gray level is assigned to 4,26 36 1,54 3,37 53 to 64 to 0. consider the gray-scale range of 0 ~ 25,[link widoczny dla zalogowanych],26 ~ 36, the purpose of lesions and more serious heavy damage to large and large effects, which were assigned 4 and 3, to distinguish it from 37 to 53 (assignment 1), 54 to 64 as normal or nearly normal, and a value of 0. the actual observation showed that while there is often heavier edema congestion and (or) bleeding, the color becomes deeper, its scope is large great impact on the body, this time, deep color, though not of blood, but the color of the areas of the Pacific, accounting for the weight in the total score will increase large, with the disease (injury) situation reflects the same. Third, on the whole lung lesion score in the study lung disease, often need to be integrated disease compared with the index, you need to make a comprehensive whole lung lesion quantification , that is,[link widoczny dla zalogowanych], a total score obtained. The score should reflect the different levels of disease and the size of each area. image analysis of lung scans, is to quickly get such accurate data. we have adopted this method blast injury, burn-blast combined injury of the lung lesions, obtained good results.
