Abstract
【解決手段】実施形態の放射線診断装置は、再構成部を備える。再構成部は、造影剤非存在下で被検体を回転撮影して収集されたX線信号から生成された収集画像と、造影剤存在下で前記被検体を回転撮影して収集されたX線信号から生成された収集画像から、血管構造の空間的連続性及び血流濃度の時間的連続性の少なくともいずれか一方を拘束条件として用いた逐次近似再構成により、前記収集画像から時系列の3次元血管画像を再構成する。
【選択図】図1
Description
第1の実施形態では、放射線診断装置の一例としてX線診断装置について説明する。まず、第1の実施形態に係るX線診断装置の構成について説明する。図1は、第1の実施形態に係るX線診断装置1の構成例を示すブロック図である。なお、X線診断装置1に、被検体P(例えば、人体)は含まれない。また、図1に示す構成は一例に過ぎない。例えば、図1に例示する各部は、適宜統合若しくは分離して構成されてもよい。
第1の実施形態では、放射線診断装置がX線診断装置1である場合について説明した。しかしながら、放射線診断装置は、X線診断装置に限定されるものではなく、例えば、X線CT(Computed Tomography)装置であってもよい。そこで、第2の実施形態では、放射線診断装置の一例としてX線CT装置について説明する。
実施形態は、上述した実施形態に限られるものではない。
