Multiview linear-array photoacoustic computed tomography with improved elevational resolution in 3D.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 reconstruct 3D images. MvFISTA-Deconv integrates the high-frequency components that correspond to high-resolution features acquired from multiple angles into the reconstructed 3D images with improved resolution. Our proposed MvLPACT is evaluated on both phantoms and in vivo human experiments, showing a significant elevational resolution improvement up to 8-fold. Our results demonstrate MvLPACT as a powerful and robust technique for high-resolution 3D imaging in PACT applications, offering substantial advancements over traditional linear-array-based PACT.
