has developed an alternative method using ultrasound. When applied to a liquid precursor, sound waves create microscopic bubbles that collapse with immense energy, triggering gel formation within ...

In this paper, the optical characteristics of an ultrasound gel lens were evaluated quantitatively by expanding the wavefront of the transmitted light in terms of the Zernike polynomial. It was ...

There's a white spot on the image, right where Bill Traynor's motor cortex is. The 70-year-old patient is lying on the MRI bed with his head inside a dome that sends focused ultrasound waves to his ...
