Photoacoustic Imaging Using a Versatile Acoustic Lens
Applications:Photoacoustic imaging (also called optoacoustic or thermoacoustic imaging) has the potential to image animal or human organs with simultaneous high contrast and high spatial resolution. The photoacoustic signal is small and needs a mechanism to focus it on an image plane without degradation. This technology improves the signal to noise...
