  • Method and apparatus for performing virtual pullback of an intravascular imaging device
    Patent number: 8913084
    Abstract: The present disclosure provides a method of simulating an intravascular procedure in a virtual environment. The method includes displaying information from a first view and a second view simultaneously. The first view contains virtual representations of an anatomical region of a human body and an intravascular imaging device disposed in the anatomical region. The second view contains a cross-sectional image of a segment of the anatomical region corresponding to a location of the intravascular imaging device. The method includes moving, in response to a user input, the virtual representation of the intravascular imaging device with respect to the virtual representation of the anatomical region. The method includes updating the cross-sectional image as the virtual representation of the intravascular imaging device is being moved. The updated cross-sectional image corresponds to a new location of the intravascular imaging device.
