Abstract: An ultrasound imaging system having an integrated touch-pad pointing device is provided. The touch-pad pointing device can be used to perform the functions currently performed by a trackball while overcoming the disadvantages commonly associated with trackballs. In addition to being integrated with the ultrasound imaging system, the touch-pad pointing device can also externally interface with the ultrasound imaging system, allowing the touch-pad pointing device to be easily added to existing ultrasound imaging systems that are not integrated with a touch-pad pointing device. Further, the touch-pad pointing device can be located on a remote user-interface device coupled with the ultrasound system to provide the further advantage of physically positioning the touch-pad pointing device closer to the user and away from the ultrasound machine.
