【摘要】 本文利用自己研制的微机图像处理系统,处理81例甲状腺扫描图,分辨率明显提高(由结节1cm以上变为0.5cm)。表明约束反卷积复原处理的效果明显高于平滑处理。通过12例手术证实处理图的结节大小与手术所见一致。病理结果表明结节异常放射性分布的程度取决于结节本身的病理变化。更多还原

【Abstract】 The results of 81 cases of thyroid scanning images processed by microcomputer image processing system we have developed are presented,The quality of the images has been greatly improved and the resolving power obviously raised (from φ 1 cm to 0.5 cm). Thus, it makes the quanlity of the hot, cool and cold nodules detected in the thyroid scanning image increased and warm nodules decreased greatly (from 24 to 1). Through comparison, it indicates that constained deconvolution restoration, the new method we’ve developed for radionuctide image processing, is much better than conventional smoothing. Operation on 12 patients demonstrated that the size of nodules were equal to the processod images. Pathological study also showed the degree of abnomal radionclide distribution depends on the pathological changes of the nodules.更多还原
