Abstract
(EN)
This image processing system (1) is provided with a reception unit (1452), an estimation unit (1351), a rendering processing unit (136), and a display control unit (1353). The reception unit (1452) receives the operation to impart virtual force to a subject represented by a three-dimensional image. The estimation unit (1351) estimates the position variation of a voxel group contained in a set of volume data on the basis of the force received by means of the reception unit (1452). The rendering processing unit (136) modifies the arrangement of the voxel group contained in the set of volume data on the basis of the estimation result of the estimation unit (1351) and newly generates a parallax image group by subjecting the modified set of volume data to rendering processing. The display control unit (1451) displays the parallax image group that was newly generated by means of the rendering processing unit (136) onto a three-dimensional display device (142).

Le système de traitement d'image (1) ci-décrit comprend une unité de réception (1452), une unité d'estimation (1351), une unité de traitement de rendu (136), et une unité de commande d'affichage (1353). L'unité de réception (1452) reçoit la commande permettant de conférer une force virtuelle à un sujet représenté par une image tridimensionnelle. L'unité d'estimation (1351) estime la variation de position d'un groupe de voxels contenu dans un ensemble de données volumétriques sur la base de la force reçue par l'intermédiaire de l'unité de réception (1452). L'unité de traitement de rendu (136) modifie l'agencement du groupe de voxels contenu dans l'ensemble de données volumétriques sur la base du résultat d'estimation de l'unité d'estimation (1351) et génère un groupe d'images parallaxes par soumission de l'ensemble de données volumétriques modifié au traitement de rendu. L'unité de commande d'affichage (1451) affiche le groupe d'images parallaxes qui vient d'être généré par l'intermédiaire de l'unité de traitement de rendu (136) sur un dispositif d'affichage tridimensionnel (142).

 実施形態に係る画像処理システム(1)は、受付部(1452)と、推定部(1351)と、レンダリング処理部(136)と、表示制御部(1353)とを備える。受付部(1452)は、立体画像が示す被検体に仮想的な力を加える操作を受け付ける。推定部(1351)は、前記受付部(1452)によって受け付けられた力に基づいて、ボリュームデータに含まれるボクセル群の位置変動を推定する。レンダリング処理部(136)は、前記推定部(1351)による推定結果に基づいて、前記ボリュームデータに含まれるボクセル群の配置を変更し、変更後のボリュームデータに対してレンダリング処理を行うことにより視差画像群を新たに生成する。表示制御部(1451)は、前記レンダリング処理部(136)によって新たに生成された視差画像群を立体表示装置(142)に表示させる。
