Photoacoustic Microscopy and Photoacoustic Computed Tomography Using High-frequency Linear Array Ultrasonic Transducers
<p>Photoacoustic tomography (PAT) is a highly promising imaging technology which forms images by detecting the induced pressure waves resulting from pulsed light absorption in biological tissues. Because the excitation source is light, PAT is a very safe, non-ionizing, and non-carcinogenic imaging …

Novel contrasts in photoacoustic tomography
<p>Photoacoustic tomography (PAT) combines rich optical contrast and high ultrasonic resolution in optically scattering tissue at depths. Taking advantage of its 100% sensitivity to optical absorption, PAT has been widely applied to structural, functional and molecular imaging, with both endogenous …
