The present invention relates to an ultrasound-based system for localizing a medical device within the field of view of an ultrasound imaging probe. A localization system is provided that includes atleast three ultrasound emitters that are arranged on a frame; and a position triangulation unit. The frame is adapted for attachment to an ultrasound imaging probe. The position triangulation unit determines a spatial position of the ultrasound detector relative to the at least three ultrasound emitters based on signals received from an ultrasound detector that is attached to the medical device. The frame includes a detachable reference volume comprising a background volume and an inclusion or void. When the detachable reference volume is attached to the frame and the frame is attached to theultrasound imaging probe the inclusion or void provides a corresponding image feature within the field of view of the ultrasound imaging probe for use in calibrating the field of view of the ultrasound imaging probe with the c
