Abstract: front page image
(EN)In one embodiment of the present invention, a method for improving a medical image quality is disclosed, comprising: determining a brightness correction factor for correcting the brightness of pixel values of a low-dose medical image using reference pixel values of a high-dose medical image; determining a noise correction factor for correcting the noise of the low-dose medical image using the reference pixel values of the high-dose medical image; and improving the quality of the low-dose medical image using the brightness correction factor and the noise correction factor.
(FR)La présente invention concerne, dans un de ses modes de réalisation, un procédé d'amélioration de la qualité d'une image médicale, comportant les étapes consistant à: déterminer un facteur de correction de luminosité destiné à corriger la luminosité de valeurs de pixels d'une image médicale à faible dose en utilisant des valeurs de pixels de référence d'une image médicale à forte dose; déterminer un facteur de correction de bruit destiné à corriger le bruit de l'image médicale à faible dose en utilisant les valeurs de pixels de référence de l'image médicale à forte dose; et améliorer la qualité de l'image médicale à faible dose en utilisant le facteur de correction de luminosité et le facteur de correction de bruit.
(KO)본 발명의 일실시예는 참조용 하이도즈 의료 영상의 화소 값들을 이용하여 로우도즈 의료 영상의 화소 값들의 밝기를 보정하기 위한 밝기 보정 계수를 결정하고, 그 참조용 하이도즈 의료 영상의 화소 값들을 이용하여 로우도즈 의료 영상의 노이즈를 보정하기 위한 노이즈 보정 계수를 결정한 후, 그 밝기 보정 계수 및 그 노이즈 보정 계수를 이용하여 로우도즈 의료 영상의 화질을 개선하는 의료 영상 화질 개선 방법을 개시한다.
