A display method for an ultrasonic image identifier comprises: when an ultrasonic transmission device performs puncture enhancement, obtaining conventional space combined image frames and large-deflection image frames (S101) performing puncture needle body identification according to image data of the large-deflection image frames, obtaining the distance from a needle body to a puncture enhancement ineffective zone, and obtaining the transparency of an ultrasonic image identifier according to the distance, the ultrasonic image identifier being used for differentiating a puncture enhancement effective zone from the puncture enhancement ineffective zone (S20) and near the needle body, naturally fusing the conventional space combined image frames and the-large deflection image frames, and displaying, according to the transparency, the ultrasonic image identifier on an ultrasonic image formed after natural fusion (S30). By means of the method, self-adaptive display of ultrasonic image identifiers can be implemented, so that a doctor can conveniently observe the effective scope of puncture enhancement. Also disclosed is a display device for an ultrasonic image identifier.Linvention concerne un procédé daffichage pour un identifiant dimage ultrasonore comprenant les étapes suivantes : lorsquun dispositif de transmission ultrasonore effectue une amélioration de perforation, obtenir des trames dimage combinées spatiales classiques et des trames dimage à déviation élevée (S10) effectuer une identification de corps daiguille de perforation selon des données dimage des trames dimage à déviation élevée, obtenir la distance séparant un corps daiguille dune zone inefficace damélioration de perforation, et obtenir la transparence dun identifiant dimage ultrasonore en fonction de la distance, lidentifiant dimage ultrasonore étant utilisé pour distinguer une zone efficace damélioration de perforation de la zone inefficace damélioration de perforation (S20) et à proximité du corps
