Photoacoustic Microscopy (PAM) offers a unique combination of high contrast from endogenous optical absorbers, and increased penetration to image microvasculature. However, images of the vasculature at increased depth are often corrupted by acoustic reverberation from superficial layers. In this paper, we present an algorithm using dictionary learning to remove the reverberant signal while preserving...
Optical Resolution Photoacoustic Microscopy (OR-PAM) is uniquely suited to preclinical imaging of the microvasculature due to its high spatial resolution (2.7 μm lateral, 46 μm axial) (Ning et al. Nature Sci. Rep.2015) and high contrast arising from endogenous optical absorption. In preclinical imaging of the mouse brain, large superficial vessels generate strong reverberant artifacts which manifest...
By continuing the control surfaces of the time-varying modifying factor analytic expression method, a new algorithm is constructed to improve the properties of the fuzzy controller obviously. The algorithm has two merits: (a) Static error is erased by fuzzy method (b) operation speed is fast. The excellent quality control and rapid response real time system can be realized together. Furthermore, the...
