Patent Images

1. A system for visualizing internal images of a body in relation to an instrument within the body, said images having been acquired by an ultrasound imaging transducer, the system comprising:

  • first spatial determinator means for determining spatial positional information of the instrument comprising a position and an orientation of the instrument in a frame of reference and for sending a first spatial signal representing the spatial positional information of the instrument;

    second spatial determinator means for determining spatial positional information of the ultrasound imaging transducer comprising a position and an orientation of the ultrasound imaging transducer in the frame of reference and for sending a second spatial signal representing the spatial positional information of the transducer;

    mapping means for receiving the first spatial signal and the second spatial signal and generating a first mapping signal indicative of the position and orientation of the instrument relative to the position and orientation of the images;

    image processing means for receiving the first mapping signal and signals representing the images acquired by the transducer and generating processed images from a view which is spatially related to the position of the instrument; and

    display means for displaying the processed images.
