项目摘要
The outline of our research results is summarized to the following four items :1.Segmentation of small pulmonary nodules (SPNs)Segmentation of SPNs on CT images accurately is an important technique for the feature characterization for differential diagnosis of SPNs. We have developed a computerized scheme for automatic segmentation of SPNs, and we can obtain precise volume data of SPNs, especially for GGO types.2.Quantitative evaluation of temporal changes for SPNsQuantitative evaluation of temporal changes for SPNs is an important for diagnosis of small lung cancers. We evaluated the doubling time of SPNs obtained from our computerized method, and we compared these results with findings reported by radiologists.3.Feature analysis for the SPNsFeature analysis of SPNs is an important for distinction between benign and malignant SPNs. The fractal dimension is a physical measure related to the complexity of object, and useful for feature analysis of SPNs. We analyzed the internal and peripheral textures of SPNs by use of fractal analysis for assisting radiologists' diagnoses.4.Temporal subtraction of whole chest CT imagesFor the diagnosis of many kinds of lung diseases, we tried making of temporal subtraction for whole chest CT images. We used rib structures for this registration.
1.肺小结节的分割准确地分割CT图像上的小结节是鉴别诊断肺小结节特征的重要技术。我们开发了一种计算机自动分割SPN的方案,可以获得精确的SPN体积数据,特别是对于GGO类型的SPN。2.SPN时间变化的定量评估SPN的时间变化的定量评估对于小肺癌的诊断具有重要意义。我们评估了从我们的计算机化方法获得的SPN的倍增时间,并将这些结果与放射科医生报道的结果进行了比较。3.SPN的特征分析SPN的特征分析是鉴别良恶性SPN的重要方法。分维是一种与对象复杂性有关的物理度量,对于SPN的特征分析是有用的。4.全胸部CT图像的临时减影对于多种肺部疾病的诊断,我们尝试对全胸部CT图像进行时间减影。我们使用肋骨结构进行登记。
