1. A system for generating a three-dimensional ultrasound scan, comprising:
- a transducer probe having elements arranged in a plurality of dimensions; and
a system controller for generating a scan line having a virtual point of emanation (VPE) in a location other than an origin projection point of said scan line.

Abstract
A system and method for individually varying the orientation of scan lines in at least two dimensions in an ultrasound scan are disclosed. In one embodiment, the invention includes a system for generating a three-dimensional ultrasound volume scan, comprising a transducer probe having elements arranged in a plurality of dimensions and a system controller capable of generating a scan line apparently emanating from a location other than the geographic center of the transducer probe.

26. A computer readable medium having a program for ultrasonically interrogating a volume, the program comprising logic for:
-
generating at least two ultrasound scan slices with a matrix transducer probe, the at least two ultrasound scan slices each including a plurality of scan lines;
where the plurality of scan lines are displaced from each other in a first dimension, and where the at least two scan slices are displaced from each other in a second dimension; and
where each of the plurality of scan lines has a virtual point of emanation (VPE) at a different point on the matrix transducer probe surface.

27. A system for generating a three-dimensional ultrasound volume scan, comprising:
-
a two-dimensional matrix transducer probe;
a system controller for generating at least two ultrasound scan lines; and
logic for instructing the system controller to generate the at least two scan lines arbitrarily displaced from each other with respect to steering angle and origin projection point.
