The present invention relates to an ultrasound diagnostic system employing a method for recognizing the positon and shape of an organ through a three-dimensional ultrasound scan to display, on a screen, a scan guide suitable for the organ, and the purpose of the present invention is to improve the convenience and accuracy of scanning by providing optimal position and angle information of an organ during a three-dimensional ultrasound scan. The present invention comprises: an ultrasound imaging unit for acquiring the information on the inside of a human body through information on an ultrasound reflected from an object an image generation unit for reconfiguring the acquired data in a three-dimensional volume form an image processing unit for providing an angle, a position, and a distance suitable for scanning by determining the absolute position and angle of the acquired image through the recognition of the organ in the generated image an image storage unit which has a plurality of sample images stored therein and stores the captured organ volume image and a display unit for providing a correction message by which the scanning angle and position with respect to the image generated in the ultrasound imaging unit can be corrected.Cette invention concerne un système de diagnostic par ultrasons employant un procédé permettant de reconnaître la position et la forme dun organe par une analyse tridimensionnelle à ultrasons en vue dafficher, sur un écran, un guide danalyse approprié pour lorgane en question. Cette invention cherche à améliorer laspect pratique et la précision de lanalyse en fournissant des informations sur la position et langle optimaux de lorgane pendant ladite analyse. Linvention comprend : une unité dimagerie à ultrasons qui acquiert des informations sur lintérieur dun corps humain par lintermédiaire de données ultrasonores réfléchies par un objet une unité de génération dimage qui reconfigure les données acquises sous forme dun volume tridimensionnel u
