Researchers Break Fundamental Barrier of Photoacoustic Imaging: Can View Capillaries at Super Resolution

Photoacoustic imaging is a way to look beneath the surface of a biological sample at high resolution. A laser is used to excite tissue, expanding it slightly and generating vibrations within it, which results in sound waves. It images better than ultrasound and at depths greater than optical techniques, revealing some pretty small objects that wou (Read more...)
