Micron resolution 3-D imaging of biological cells with ultrasound

Researchers have described the first known demonstration of 3-D cell imaging using picosecond ultrasonics, and show that picosecond ultrasonics can achieve micron resolution of single cells, imaging their interiors in slices separated by 150 nanometers. This work is a proof-of-principle that may open the door to new ways of studying the physical properties of living cells by imaging them in vivo.
