Guidance of invasive medical devices by wide view three dimensional ultrasonic imaging

摘要

A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device ( 30 ) in three dimensions. The invasive medical device ( 30 ) is shown in a detailed ultrasonic image and the balance of the volumetric region ( 120 ) in which the device is located is shown in a wide field of view. The detailed and wide fields of view may be displayed separately or overlapping in spatial alignment on an image display ( 18 ). The wide field of view may be shown in two or three dimensions. A quantified display may be shown together with the wide and detailed anatomical displays. The detailed view may also be shown in an enlarged or zoomed format.
