ABSTRACT:
The invention provides an intracavitary ultrasonic scanner with a helical scan. Mechanical and electronic steerable array implementations of the helical scan are described. A plastic cover sheath, filled with coupling fluid, covers the probe of the scanner. Portions of probe are porous allowing the coupling fluid to penetrate to the outside of the sheath. An improved polar coordinate decoding system provides an accurate control of the scan and allows storage of scan information in voxel memory.
