A remote control method for an ultrasonic diagnostic instrument, comprising: a portable remote control terminal sending verification information comprising identity recognition to a target ultrasonic diagnostic instrument (120) the target ultrasonic diagnostic instrument judging whether the portable remote control terminal possesses a remote control authority (220) when the portable remote control terminal possesses the remote control authority, the target ultrasonic diagnostic instrument sending response information comprising remote control interface data to the portable remote control terminal (230) and the portable remote control terminal presenting a remote control interface according to the received remote control interface data (140), so as to realize remote control. On one hand, since the target ultrasonic diagnostic instrument needs to verify the identity of the portable remote control terminal in advance, the confusion of remote control is avoided. On the other hand, since the response information received by the portable remote control terminal comprises the remote control interface data, the remote control interface is targeted. Also provided are a portable remote control terminal and a target ultrasonic diagnostic instrument in accordance with the remote control method.Linvention concerne un procédé de commande à distance pour un instrument de diagnostic à ultrasons, le procédé comprenant les étapes suivantes: un terminal de commande à distance portatif envoie des informations de vérification comprenant une reconnaissance didentité à un instrument de diagnostic à ultrasons cible (120) linstrument de diagnostic à ultrasons cible évalue si le terminal de commande à distance portatif possède une autorité de commande à distance (220) lorsque le terminal de commande à distance portatif possède lautorité de commande à distance, linstrument de diagnostic à ultrasons cible envoie des informations de réponse comprenant des données dinterface de commande à distan
