Photoacoustic computed microscopy [PDF]
Scientific Reports, 2014 Photoacoustic microscopy (PAM) is emerging as a powerful technique for imaging microvasculature at depths beyond the ~1 mm depth limit associated with confocal microscopy, two-photon microscopy and optical coherence tomography. PAM, however, is currently qualitative in nature and cannot quantitatively measure important functional parameters including ...

Super-resolution photoacoustic fluctuation imaging with multiple speckle illumination [PDF]
, 2015 In deep tissue photoacoustic imaging, the spatial resolution is inherently limited by acoustic diffraction. Moreover, as the ultrasound attenuation increases with frequency, resolution is often traded-off for penetration depth.

Photothermal therapy and photoacoustic imaging via nanotheranostics in fighting cancer.
Chemical Society Reviews, 2019 The nonradiative conversion of light energy into heat (photothermal therapy, PTT) or sound energy (photoacoustic imaging, PAI) has been intensively investigated for the treatment and diagnosis of cancer, respectively. By taking advantage of nanocarriers,
