The current method of emulsifying tissue employs focused ultrasound with microsecond pulses and cavitation. This invention emulsifies soft tissue using a mechanism of ultrasonic atomization inside gas or vapor cavities.

The method of non-invasively treating tissue includes pulsing ultrasound energy from the ultrasound source toward the target site in the tissue. The ultrasound source is configured to emit high-intensity focused ultrasound (HIFU) waves. The target site comprises a pressure-release interface of a gas or vapor cavity located within the tissue.

The method continues by generating shock waves in the tissue to induce a lesion at the target site. It additionally includes characterizing the lesion based on a degree of at least one of a mechanical or thermal ablation of the tissue.

This work was done by Oleg Sapozhnikov, Michael Bailey, Tatiana Khokholova, Vera Khokholova, and Julianna Simon of the University of Washington for Johnson Space Center. NASA is seeking partners to further develop this technology through joint cooperative research and development.
