Multiview linear-array photoacoustic computed tomography with improved elevational resolution in 3D.

ABSTRACT: Linear transducer arrays are widely used in photoacoustic computed tomography (PACT) due to their lightweight design, cost-effectiveness, and handheld convenience. Despite these advantages, the inherent focusing design of the linear array results in anisotropic resolution in 3D. Specifically, the elevational resolution is approximately an order of magnitude worse than both lateral and axial resolutions. In this work, we propose multiview linear PACT (MvLPACT) to overcome this limitation. By combining the scanned data along the elevational direction from multiple angles, MvLPACT compensates for the deficiencies in elevational resolution. A multiview fast iterative shrinkage-thresholding algorithm (FISTA) based deconvolution, named MvFISTA-Deconv, is applied to the multiview scanning data to
