Outline of Final Research Achievements |
This study focused on non-linear registration of serial body CT images to attain high accuracy. The algorithm used was large deformation diffeomorphic metric mapping (LDDMM) besed on the Euler-Lagrange equation. In lung tumor cases, changes in the size, disappearance or appearance of the tumors could be evaluated by the automatic processing. In the abdomen and pelvis, the proposed method found bone metastasis, which may not necessarily be detected by conventional evaluation. The proposed method is expected to bring objective and accurate evaluation into clinical practice.
