<p>A control device (1 18) includes a position sensing component (202) that senses a position of the control device relative to a free space coordinate system and generates a signal indicative thereof, and a transmitter (210) that transmits the signal to an imaging system that employs the signal to position a graphical cursor on a display of the imaging system in coordination with the position of the sensing component in free space. An imaging apparatus (100) includes a scanner (102), including an interface (108) configured to connect with a complementary interface of an imaging transducer probe. A display (1 16) presents information indicative of a signal sensed by the imaging transducer probe. A processor (224) generates and positions a graphical cursor of a display region of the display based on a position of a control device, which is registered to operate the scanner, in free space.</p> |
