19 Claims

1. A method of ultrasonically displaying an invasive medical device and the volumetric region of a body in which it is located comprising:

scanning the volumetric region with beams transmitted by an ultrasonic array transducer;

receiving echo signals from the volumetric region and from an invasive medical device located in the region;

processing echo signals to produce a wide field of view of the volumetric region;

processing echo signals to produce a detailed view of the portion of the volumetric region in which the invasive medical device is located; and

displaying both the wide field of view of the volumetric region and the detailed view of the portion of the volumetric region in which the invasive medical device is located in spatial alignment in a common image on an image display.
