Three Dimensional Imaging for Guiding Interventional Medical Devices in a Body Volume
First Claim
1. An imaging system for generating for display live, three-dimensional images of a body volume, the system comprisingtwo dimensional array transducer for scanning said body volume so as to obtain live three-dimensional images in respect of said body volume,object recognition means for identifying, within one or more of said live three dimensional images of said body volume, the relative location of a selected object within said body volume,means for selecting an imaging plane corresponding to said location of said object, andmeans for generating a live three-dimensional image intersected by a delineation of said selected imaging plane containing the location of the object.

Abstract
The present invention relates to an intervention guidance system in which the location of an interventional medical device (30) within a body volume is determined by image processing means (14) from live, three-dimensional ultrsound images thereof, and this localisation is used to generate a control signal for steering an ultrasound beam (20) so as to alter the imaging plane (or region of interest 235) in accordance with the relative location within the body volume of the intervention device (30). The use of image processing techniques to localise the intervention device (30) obviates the need for specific locations on the device.
