| Outline of Final Research Achievements |
Statistical Shape Model (SSM) of a target organ quantitatively describes individual differences of the organ shapes using their average and variance. By deforming the SSM to fit an organ shape of a patient, the organ shape enables to be represented by a small number of parameters. Although conventional SSM constructions have focused on only motionless organs such as bones, there are few SSMs for a heart that describe the deformation of the heart. Therefore, we constructed a multi-dimensional SSM for the heart that considers not only shape differences among individuals but also sequential deformation within the cardiac cycle.

構築した多元心臓SSMを各患者の臓器形状に合わせて変形することで，患者固有の心臓形状を，少数のパラメータで定量的に表現できる．得られたパラメータを用いることで，患者の臓器形状に適した治療・診断システムの構築が可能となり，心疾患に対する治療・診断精度を飛躍的に向上できる可能性がある．
