"PET/MRI統合スキャナ開発の要素技術のひとつとして生体組織による放射線吸収をMRI画像を基に補正する手法が提案されている。MRI画像により吸収係数が異なる組織に区分することはできるが、減弱係数そのものを求めることはできない。そこで、吸収係数の代表値が用いられるが、個人差による誤差の影響が懸念される。本研究では特に定量性が重要視される脳PET画像に吸収係数の誤差が及ぼす影響について検討した。特に、脳組織に割り当てる吸収係数の誤差がPETの画素値に最も大きく影響を及ぼすことがわかった。MRI画像に基づく吸収補正においては領域分割の精度に加え、割り当てる吸収係数の精度も重要であることが示された。",
