SYSTEM AND METHOD FOR FIVE PLUS ONE DEGREE-OF-FREEDOM (DOF) MOTION TRACKING AND VISUALIZATION

摘要

A method for manipulating a remote device with a hand-held device having one or more first sensors to detect angular orientation of the device in one or more planes, and at least one two-dimensional surface device having one or more second sensors to detect translational position of the hand-held device in one or more directions, which communicates the angular orientation data from the hand-held device and the translational position data from the at least one surface device to the remote device, and positions the remote device based on the angular orientation data from the hand-held device and the translational position data from the at least one surface device.

1. A method for manipulating a remote ultrasound imaging system comprising:
providing a hand-held device having three first sensors to detect angular orientation of the device in three planes, providing a two-dimensional surface of a personal computer table or laptop laid flat on a fixed counter or tabletop, said surface having two second sensors to detect translational position of the hand-held device in two directions, displaying an image on said surface taken from the remote ultrasound imaging system, providing a pressure sensor on or in the hand-held device to communicate compression data to the remote device, communicating the angular orientation data and compression data from the hand-held device and the translational position data from the surface device to a remote host that controls the position and angular orientation of the remote device, using the compression data to calculate translational position data in a dimension approximately orthogonal to the translational position data from the surface device, and positioning a remote ultrasound imaging device based on the angular orientation data and pressure data from the hand-held device and the translational position data from the surface device.
