Articles:
8 Applications of Transcranial Focused Ultrasound Surgery—Daniel Pajek and Kullervo Hynynen
Focused ultrasound surgery is capable of non-invasively ablating precise regions within the brain.
15 Photoacoustic Imaging for Medical Diagnostics— Carolyn L. Bayer, Geoffrey P. Luke,
and Stanislav Y. Emelianov
Improved medical diagnosis based on real-time, non- invasive in vivo anatomical, functional and molecular visualization of living tissue may soon be possible with ultrasound-guided photoacoustic imaging, a technology which is currently being tested in both preclinical and clinical settings.

Michael Bailey, Lawrence Crum, Zhen Xu,
Brian Fowlkes, Charles Cain, and Vera Khokhlova
Focused ultrasound can induce targeted mechanical destruction of soft tissues for bloodless surgery.
38 Ultrasonic Bioeffects on Peripheral Nerves—
Robert Muratore and Jeffrey J. Vaitekunas
The response of the peripheral nervous system to ultra- sound is shaped by five principles: efficacy over an extremely wide range of acoustic parameters, the neces- sity to target just a small portion of a nerve, non-monot- onic behavior with increasing dose, differential sensitivi- ty among the various fibers within a nerve, and multi- ple, complex mechanisms of interaction.
