Method and system for performing real time navigation of ultrasound volumetric data

An ultrasound system is provided that includes a display processor that accesses data volumes stored in an image buffer successively to control generation of at least one of 2D and 3D renderings based on display parameters. The display processor obtains from the image buffer a first data volume defined based on first scan parameter values, while a probe acquires ultrasound information for a second data volume that is entered into the image buffer. The second data volume is defined based on second scan parameter values. A navigation view presents in real time the renderings generated by the display processor with their corresponding 31) orientation. A navigator is provided that controls the display of the navigation view in real time such that, as the user adjusts a display parameter value to change a view plane, images presented in the navigation view are updated to reflect the view plane.
