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 ...
1064 nm acoustic resolution photoacoustic microscopy
Photoacoustic imaging is a noninvasive imaging technique having the advantages of high-optical contrast and good acoustic resolution at improved imaging depths. Light transport in biological tissues is mainly characterized ...
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 ...
Photoacoustic imaging depth comparison at 532-, 800-, and 1064-nm wavelengths : Monte Carlo simulation and experimental validation
Photoacoustic imaging (PAI) provides high-resolution and high-optical-contrast imaging beyond optical diffusion limit. Further improvement in imaging depth has been achieved by using near-infrared window-I (NIR-I, 700 to ...
