1. A method for generating a 2-dimensional ultrasound image in a 3-dimensional viewing environment, the method comprising:
- mounting a plurality of mobile transducer means to an ultrasound image transducer means adapted for generating a 2-dimensional echo image plane;
mounting a first reference transducer means to a first fixed location;
mounting a second reference transducer means to a second fixed location;
generating three-dimensional coordinates of the mobile transducer means relative to a reference frame established by the first and second reference transducer means;
registering the 2-dimensional echo image plane with the three-dimensional coordinates; and
,displaying the 2-dimensional echo image plane at the three-dimensional coordinates, in relation to the reference frame established by the first and second reference transducer means.

Abstract
A system for displaying a 2-D ultrasound image in a 3-D viewing environment. Within the same 3-D viewing environment, various surgical instruments can be tracked and displayed, thus correlating 3-D virtual surgery with ultrasound imaging for verification. A detachable housing (220) containing position transducers (222) is attached to a conventional 2-D ultrasound imaging head (200) to provide position data of an imaging plane generated by an image transducer (204).
