BUBBLE CLOUD BEHAVIOR AND ABLATION CAPACITY FOR HISTOTRIPSY GENERATED FROM INTRINSIC OR ARTIFICIAL CAVITATION NUCLEI

Connor Edsall et al.

Summary: The study found that artificial cavitation nuclei, such as microbubbles and nanocones, can significantly reduce the cavitation threshold for histotripsy compared to intrinsic nuclei, creating predictable and well-defined bubble clouds. In red blood cell experiments, intrinsic nuclei and nanocone models showed complete tissue ablation, while microbubble models only achieved partial ablation.
