This study explores a technique for light manipulation using an acoustic vortex generated by a high-intensity focused ultrasound transducer. The acoustic vortex forms a ring of bubble wall near the high-pressure region, creating a lens-like structure that can effectively focus a laser beam. The effects of varying acoustic pressures and dissolved oxygen content on the focused ultrasound and vortex waveforms were tested.

Article Synopsis
- Using acoustic vortex tweezers (AVT) helps collect microbubbles for better drug delivery and improved ultrasound imaging, but challenges like fluid flow restrictions and spatial resolution exist.
- To overcome these issues, researchers combined AVT with volumetric super-resolution imaging (VSRI) to monitor microbubble clusters in real-time while maintaining a steady flow rate.
- The new technique, involving an asymmetrical AVT waveform, successfully gathered microbubbles without repelling them and showed better dynamic tracking capabilities compared to traditional imaging methods.
