ADAPTIVE ABERRATION CORRECTION OF ABDOMINAL IMAGES USING PARCA

Clinical images of the abdomen may be degraded by aberrations due to p ropagation through the abdominal wall, resulting in loss of contrast a nd reduction in overall image quality. The Parallel Adaptive Receive C ompensation Algorithm (PARCA) uses multiple receive beams to compensat e for these aberrations. Previous studies have demonstrated that PARCA can restore image quality in tissue-equivalent phantoms scanned with controlled phase and amplitude fluctuations. In this study, PARCA is u sed to improve clinical images of the abdomen. PARCA processed images show both improved contrast of structures and improved overall image q uality. (C) 1997 Dynamedia, Inc.
