Impact of sensor apodization on the tangential resolution in photoacoustic tomography
Photoacoustic tomographic (PAT) image reconstruction with apodized sensors is discussed. A Gaussian function was used to model axisymmetric apodization of sensors and its full width at half maximum (FWHM) was varied to ...
Metabolizable semiconducting polymer nanoparticles for second near-infrared photoacoustic imaging
Photoacoustic (PA) imaging in the second near‐infrared (NIR‐II) window (1000–1700 nm) holds great promise for deep‐tissue diagnosis due to the reduced light scattering and minimized tissue absorption; however, exploration ...
Pulsed laser diode based desktop photoacoustic tomography for monitoring wash-in and wash-out of dye in rat cortical vasculature
Photoacoustic (PA) tomography (PAT) imaging is an emerging biomedical imaging modality useful in various preclinical and clinical applications. Custom-made circular ring array-based transducers and conventional bulky ...
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 ...
