| Outline of Final Research Achievements |
In this study, a registration method for finding correspondences between feature points of MR and CT images was investigated, using a principal motion pattern model which is applicable for even COPD (Chronic Obstructive Pulmonary Disease) or IP (Interstitial Pneumonia). A new pulmonary blood flow analysis for contrast-enhanced MR was then developed, based on a two-input model including the pulmonary artery and the recirculation from the aorta into the lung. We have also proposed a multi-modality MR-CT integration using lung vessel determination. Then, an automated anatomy structure segmentation method, such as the lobe, airway tree and pulmonary vessel tree, in a chest CT was developed, based on newly proposed a failure tracking and recovery algorithm.
Integrating the proposed methods, we have also developed a prototype system to investigate diffuse lung diseases diagnosis and/or blood flow distributions in each lung structure, in order to evaluate the availability for clinical uses.
