Digital Processing of Acoustical Holograms

  • C. S. Clark
  • A. F. Metherell


Acoustical holograms recorded at 1 MHz using the McDonnell Douglas medical imaging system were digitized into 1024 × 1024 elements and 64 grey levels (6 bits). Digital processing, similar to that used in conventional digital image processing, was employed in the acoustical hologram plane rather than the reconstructed image plane to improve the image signal-to-noise ratio and to perform other image manipulations. The analysis and experimental results obtained comparing processed and unprocessed images are presented.
