摘要
Previous studies have shown that the parallel adaptive receive compensation algorithm (PARCA) can improve clinical images of the abdomen degraded by aberrations. Corrected images show both improved contrast resolution and overall image quality. However, PARCA is very computationally intensive and, consequently, cannot be easily implemented in real-time. In this study, modifications to PARCA for possible real-time implementation are explored. A modified algorithm, PARCA2 (parallel adaptive receive compensation algorithm 2), is introduced to perform aberration correction much more efficiently. Results from tissue-mimicking phantoms and human images show that corrections with PARCA2 rival that of PARCA.
