The purpose of the present invention is to provide a tomographic image data processing system and a tomographic image data processing method, which minimize data capacity of a tomographic image acquired through CT or MR photographing so as to reduce the processed data and storage capacity of the tomographic image, and enable the tomographic image to be quickly reconstructed so as to increase a processing speed, thereby improving overall data processing efficiency for the tomographic image. To this end, the present invention provides a tomographic image data processing system for processing image data acquired through tomography, the system comprising: a tomographic image receiving/storing unit for receiving n-number of tomographic images and storing the received images； an image processing unit for processing the tomographic images stored in the receiving/storing unit so as to generate a difference image, having a pixel difference with respect to time-series images, from the tomographic images stored in the receiving/storing unit； a compressing/storing unit for compressing and storing data of the received image, and compressing and storing data of the difference image； and a reconstruction and display unit for receiving the difference image of the compressing/storing unit and a reference image for the difference image, and associating the difference image and the reference image so as to reconstruct and display n-number of images.La présente invention a pour objet de concevoir un système et un procédé de traitement de données d'images tomographiques qui réduisent à un minimum la capacité de données d'une image tomographique acquise par TDM ou IRM de manière à réduire la capacité de données traitées et de mémorisation de l'image tomographique, et permettent une reconstruction rapide de l'image tomographique de façon à augmenter une vitesse de traitement, améliorant ainsi l'efficacité globale de traitement de données de l'image tomographique. À cet effet, la présente
