The present invention relates to a method of image building centralization comprising a step of acquiring at least one radiofrequency signal by a sensor (2; 2 ') of at least one local imaging device (1; 1 '), a step of transmitting (I, II, III, IV :: I', II ', III', IV ')) the radiofrequency signal from the sensor (2,2') to a central processing unit ( 8), a step of processing said radio frequency signal to construct an image, and a step of transmitting (V, VI; V ', VI') of the constructed image to a display (4,4 ') of said device acquisition method (1,1 '), characterized in that the transmission (I, II, III, IV ;, I', II ', III', IV ') between the sensor (1,1') and said unit of processing (8) and transmission (V1VI; V1VI ') between said processing unit (8) and the display (4,4') are performed via a telecommunications network (7), and in that prior to said step of transmitting (I, II, III, to said unit of In processing (8), the radiofrequency signal from said sensor (2, 2 ') is converted into a format compatible with the telecommunications network (7). The present invention also relates to an image building centralization system implementing such a method.La présente invention concerne un procédé de centralisationde construction d'images comportant une étape d'acquisitiond'au moins un signal de radiofréquence par un capteur (2;2') d'au moins undispositif d'imagerie local (1;1 '), une étape detransmission (I, II, III, IV::I', II', III', IV')) du signal de radiofréquenceissu du capteur (2,2') à une unité de traitement centralisée(8), une étape de traitement dudit signal de radiofréquence en vue deconstruire une image, et une étape de transmission (V,VI;V',VI') de l'image construite à un afficheur (4,4') dudit dispositifd'acquisition (1,1 '), caractérisé en ce que la transmission (I, II,III, IV;;I',II',III',IV') entre le capteur (1,1 ') et ladite unité detraitement (8) et la transmission (V1VI; V1VI') entre ladite unité detraitement (
