Sparsity-based beamforming to enhance two-dimensional linear-array photoacoustic tomography
In linear-array photoacoustic imaging (PAI), beamforming methods can be used to reconstruct the images. Delay-and-sum (DAS) beamformer is extensively used due to its simple implementation. However, this algorithm results ...
An efficient image formation algorithm for real-time linear-array photoacoustic tomography
In photoacoustic (PA) imaging using commercial ultrasound transducers, two dimensional PA images are pro-duced by commonly used delay-and-sum (DAS) as the reconstruction method. However, the reconstructed image is a ected ...
Genetic algorithm for feedback-based wavefront shaping in optical imaging
Traditional optical devices rely on light propagation along a straight path. However, when the light propagates through a blurred medium, its direction get scattered by microscopic particles. This inhomogeneous distortion ...
