Abstract
(EN) This image processing system generates an X-ray image by processing a reading signal read from an image plate in which an X-ray captured image has been recorded. The image processing system performs, with respect to the entire output region included in the reading signal, signal processing such that the degree of variation in shade in a region of interest part corresponding to the purpose of observation is higher than the degree of variation in shade in a region of non-interest which is other than the region of interest.
(FR) Ce système de traitement d'image génère une image radiographique par traitement d'un signal de lecture lu à partir d'une plaque d'image sur laquelle une image capturée par rayons X a été enregistrée. Le système de traitement d'image réalise, par rapport à la totalité de la région de sortie comprise dans le signal de lecture, un traitement de signal de telle sorte que le degré de variation de nuance dans une partie de région d'intérêt correspondant à l'objet de l'observation est supérieur au degré de variation de nuance dans une région sans intérêt qui est autre que la région d'intérêt.
(JA) 画像処理システムは、X線撮影画像が記録されたイメージプレートから読み取られる読取信号を処理してX線画像を生成する。画像処理システムは、読取信号に含まれる全出力域に対し、観察の目的に応じた一部の注目域に関する濃淡の変化度合いが、注目域以外の非注目域に関する濃淡の変化度合いよりも大きくなるように信号処理を行う。
