Title (EN) MEDICAL IMAGING DEVICE AND MEDICAL IMAGE PROCESSING METHOD
(FR) DISPOSITIF D'IMAGERIE MÉDICALE ET PROCÉDÉ DE TRAITEMENT D'IMAGE MÉDICALE
(JA) 医用撮像装置及び医用画像処理方法
Abstract:
(EN) Provided is a medical imaging device that employs a novel image reconstruction technique in which DL is applied to medical image processing, significantly reducing the total imaging time including the time for image reconstruction and enabling the capture of a high-quality medical image in a short time. A medical image is classified into any of a plurality of predetermined kinds. One or more optimal restorers are selected on the basis of the classification results from a plurality of restorers, each thereof corresponding to each of the plurality of kinds. A reconstruction process is performed using the selected restorer. For example, the medical image is divided into a plurality of patches, and the patches are independently subjected to the reconstruction process and integrated. The restorers can be configured with a CNN.
(FR) L'invention concerne un dispositif d'imagerie médicale qui utilise une nouvelle technique de reconstruction d'image dans laquelle une DL est appliquée au traitement d'image médicale, pour réduire ainsi significativement le temps d'imagerie total y compris le temps de reconstruction d'image et permettre la capture d'une image médicale de qualité élevée en un court laps de temps. L'image médicale est classée selon une pluralité de types prédéfinis. Un ou plusieurs dispositifs de reconstruction optimaux parmi une pluralité de dispositifs de reconstruction sont sélectionnés en fonction des résultats de la classification, chacun correspondant à un type de ladite pluralité de types et un processus de reconstruction est mis en œuvre à l'aide du ou des dispositifs de reconstruction sélectionnés. Par exemple, l'image médicale est divisée en une pluralité de parties, et les parties sont indépendamment soumises au processus de reconstruction et intégrées. Les dispositifs de reconstruction peuvent être conçus à l'aide d'un CNN.
(JA) 医用画像処理にDLを適用した新規な画像再構成技術を適用し、画像再構成時間を含めた全撮像時間の大幅な短縮を図り、短時間で高画質の医用画像を取得可能な医用撮像装置を提供する。 医用画像を予め定めた複数の類のいずれかに分類し、複数の類のそれぞれに対応する複数の復元器から、分類結果に応じて最適な1ないし複数の復元器を選択し、選択した復元器を用いて再構成処理を行う。医用画像は、例えば、複数のパッチに分けられ、パッチ毎に再構成処理を行い、統合される。復元器は、CNNで構成することができる。
