Efficient parallel adaptive aberration correction

摘要

Previous studies have shown that the parallel adaptive receivencompensation algorithm (PARCA) can improve clinical images of thenabdomen degraded by aberrations. Corrected images show both improvedncontrast resolution and overall image quality. However, PARCA is veryncomputationally intensive and, consequently, cannot be easilynimplemented in real-time. In this study, modifications to PARCA fornpossible real-time implementation are explored. A modified algorithm,nPARCA2 (parallel adaptive receive compensation algorithm 2), isnintroduced to perform aberration correction much more efficiently.nResults from tissue-mimicking phantoms and human images show thatncorrections with PARCA2 rival that of PARCA
