A system for guiding a user in ultrasound assessment of a fetal organ so as to perform a diagnostic evaluation of the fetal organ development during a medical examination, said ultrasound assessment being based on an ultrasound images sequence comprising multiples predefined required views of the fetal organ, said system comprising: - input module configured to receive: o in real time a sequence of 2D ultrasound images, said images comprising multiple predefined required views of the fetal organ, wherein each image comprises at least a portion of the fetal organ; o a predefined list of view's categories, wherein each view's category is associated to at least one predefined fetal anatomical landmark; - an image analysis module configured to, for each image: o provide the image as input to an image analysis structure comprising at least one first classifier (DL1a), said first classifier (DL1a) being configured to identify whether the image belongs to any view's category comprised in the predefined list of view's categories and, if so, to identify the view's category to which belongs the image among said predefined list of view's categories; o provide the image as input to a second classifier (DL1b) of the image analysis structure, said second classifier (DL1b) being configured to detect the presence of predefined fetal anatomical landmarks in the image; o add the image to a valid images list whenever: ▪ the first classifier (DL1a) identifies that the image corresponds to one view's category of the predefined list of view's categories; and ▪ the second classifier (DL1b) identifies that a predefined number of fetal anatomical landmarks are present in the image, said fetal anatomical landmarks being associated to said one view's category identified by the first classifier; o providing the valid images list. - input module configured to receive: o in real time a sequence of 2D ultrasound images, said images comprising multiple predefined required views of the fetal organ, wherein each image comprises at least a portion of the fetal organ;
