Abstract

The problem of producing real-time, 3-D (volumetric) ultrasonic images can be divided into two main tasks: (1) acquiring 3-D echo data from a target volume in a sufficiently short time, and (2) reducing this 3-D data set into a suitable 2-D image. Both of these tasks can be accomplished simultaneously by a method, dubbed `Slit-O-Vision,' wherein a diverging lens is used to expand the (normally collimated) elevation beam pattern of a conventional linear or phased array transducer into a `fan beam.' The 2-D images produced in this manner make an object in the target volume appear three-dimensional, because the fan beam integrates the echoes at a given range across the entire `slice thickness' of the tomogram, thus projecting (collapsing) the volumetric echo data into a single 2-D projection image. This also allows the volumetric image to be updated 30 times per second. Slit-O-Vision may be useful in medical or sonar imaging applications.
