Description
図1は、第1の実施形態に係る医用画像処理装置を含む医用画像処理システムの構成例を示す模式図であり、図2は同実施形態に係るテリトリーマップ記憶部に記憶されるテリトリーマップの一例を示す模式図である。図1に示す医用画像処理システム1は、医用画像処理装置10と、CT(Computed Tomography)装置20及びPACS(Picture Archiving and Communication System)30とが、例えばLAN(Local Area Network)や公衆電子通信回線等のネットワーク40を介して通信可能に接続されたシステムである。このため、医用画像処理装置10には、CT装置20及びPACS50との通信を可能にする通信インターフェース103が設けられている。
図11は第2の実施形態に係る医用画像処理装置を含む医用画像処理システムの構成例を示す模式図である。図11に示す医用画像処理システム1は、医用画像処理装置10と、CT(Computed Tomography)装置20、MRI(Magnetic Resonance Imaging)装置30、核医学診断装置40及びPACS(Picture Archiving and Communication System)50とが、例えばLAN(Local Area Network)や公衆電子通信回線等のネットワーク60を介して通信可能に接続されたシステムである。このため、医用画像処理装置10には、CT装置20、MRI装置30、核医学診断装置40及びPACS50との通信を可能にする通信インターフェース103が設けられている。
次に、第3の実施形態に係る医用画像処理装置について、上記した図11を用いて説明する。本実施形態は、第2の実施形態に示す医用画像処理装置10に、冠動脈内の狭窄部位が治療対象狭窄であるか又は治療非対象狭窄であるかを判定する機能を付加したものである。なお、以下では、図18のフローチャートと図19の模式図とを参照しながら、第2の実施形態とは異なる機能についてのみ説明する。つまり、ステップS21乃至S28の処理は、上記した第2の実施形態と同様であるため、ここでは詳細な説明は省略し、以下では、ステップS30乃至S36の処理について主に説明する。
