Image diagnosis in hospital using Personal Computer

As an example of image analysis and diagnosis which are done in use of personal compute in the hospital, we indtroduce a quantitative analysis of pulmonary emphysema. The cause of pulmonary emphysema is smoking and this disease expands bronchiolar and alveolar besides destroying them. The criteria (standardization) of qualitative evaluation and diagnosis in use of computed tomography with few stimulation are expected on this account. We use the NIH Image, an image soft of personal computer, and carried out quanlitatve grasp of picture of inspiratory and expiratory of lungs both healthy and emphysema The evaluation index of emphysema was shown at the meeting for the study of pulmonary emphysema in 1999, and with this index, we tried a comparison and reevaluation of our analysis result of NIH Image.
