Volumetric imaging with ultrasonic spiral CT.

To examine the feasibility of implementing spiral computed tomography (CT) in ultrasonic imaging as a potential method for breast screening, an algorithm for x-ray spiral CT was applied to ultrasonic waves on a specially built ultrasonic tomographic system. Three-dimensional reconstructions of various phantoms were obtained. Spiral ultrasonic CT is feasible, and it may have clinical merit as a breast imaging method.
