Abstract
A volume is represented using high spatial resolution ultrasound data. By modulating B-mode data with Doppler or flow information, the spatial resolution or contrast of the B-mode data may be enhanced. The same set of ultrasound data is used for identifying a boundary, for placing the perspective position within the volume and rendering from the perspective position. The identification of the boundary and rendering are automated or performed by a processor. Ultrasound data may be used for generating three-dimensional fly-through representations, allowing for virtual endoscopy or other diagnostically useful views of structure or fluid flow channel. Virtual processes are not invasive, allow for more patient comfort, have selectable or different depths of focus, may allow for fly-through of different types of anatomy and may be used as a training tool.
