Outline of Research at the Start

人体臓器形状の個体差を,形状の平均や分散を用いて定量化することで,個体差を考慮したコンピュータ支援治療・診断システムの構築が可能となる.動きのない臓器(例:骨)に対する定量的記述法として,統計的形状モデル(Statistical Shape Model: SSM)が既に確立されている.一方,動きのある臓器(例:心臓)における,臓器自身の変形まで考慮した記述法はこれまでない.そこで,申請者は,心臓を対象として,臓器形状の個体間差のみでなく,臓器の動きまで考慮した新しい定量的記述法,多元心臓SSMの構築を行う.これにより,患者固有の心臓変形情報が得られ,治療・診断システムの精度向上が期待できる.

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.

Academic Significance and Societal Importance of the Research Achievements

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.
