An ultrasonic image processing system comprising: a data receiving module (110) for acquiring multiple groups of three-dimensional image data corresponding to a single target tissue； an image analyzing module (130) for dividing, on the basis of any one group of the multiple groups of three-dimensional image data, a target region to obtain a three-dimensional volume structure boundary of the target region, and a safety boundary generated by outward expansion or inward contraction along the three-dimensional volume structure boundary； an image mapping module (120) for establishing a spatial mapping relation between the multiple groups of three-dimensional image data, and according to the spatial mapping relation, mapping the three-dimensional volume structure boundary and the safety boundary of the target region to the other groups of three-dimensional image data； and an image marking module (150) for marking, in a displayed image, corresponding three-dimensional volume structure boundaries and safety boundaries of the target region in the multiple groups of three-dimensional image data, or regions within the three-dimensional volume structure boundaries and safety boundaries. The system is capable of solving the problem in the prior art in which collection, analysis and quantitative display cannot be performed on the ultrasonic images during the treatment process.La présente invention concerne un système de traitement d'image ultrasonore comprenant : un module (110) de réception de données permettant d'acquérir de multiples groupes de données d'image tridimensionnelle correspondant à un seul tissu cible ； un module (130) d'analyse d'image destiné à diviser, sur la base d'un groupe quelconque parmi les multiples groupes de données d'image tridimensionnelle, une région cible afin d'obtenir une limite de structure volumique tridimensionnelle de la région cible, et une limite de sécurité générée par l'expansion vers l'extérieur ou la contraction vers l'intérieur le long
