Passive cavitation imaging with p th root coherence factor and sparse arrays: In vitro and in vivo assessment for histotripsy monitoring

Key Points

• The main aim is to assess the effectiveness of pCFwDSI in enhancing imaging capabilities for histotripsy monitoring.
• In vitro and in vivo assessments were conducted.
• Passive cavitation imaging techniques were applied using pCFwDSI.
• Performance metrics like axial resolution and artifact reduction were analyzed.
• Improved axial resolution observed with pCFwDSI.
• Reduction in imaging artifacts noted.
• Achieved clinically-relevant frame rates without increased computational load.
