Investigation of ultrasound plane-wave imaging for optimal synthetic focusing.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Plane-wave imaging for ultrafast ultrasound, revolutionized by substantially enhancing frame rates, has paved the way for numerous applications in medical ultrasound. To improve spatial resolution and contrast, plane-wave compounding is typically utilized. Plane-wave compounding, referred to as plane-wave synthetic focusing (PW-SF) in this study, coherently sums the echoes from plane waves steered at multiple angles. To further improve the image quality and reduce the computational complexity for PW-SF, this study investigates the impact of plane-wave angle distributions and beamforming grids. Plane-wave angles with evenly selected in the radian space and in the sine of radian space, referred to as θ-even and α-even angles, respectively, are analytically derived. For the beamforming grids, we apply a plane-wave pixel-based synthetic focusing (PW-PBSF) approach, directly focusing echoes on display pixels, to achieve the optimal image quality in terms of resolution and computational complexity. From the simulation and phantom experiment, the largest improvement in lateral resolution was observed with PW-PBSF [0.16 mm], which produced 0.29 mm compared with 0.35 mm for PW-SF-256, corresponding to approximately a 17% enhancement. The α-even angle discretization approach also provided higher contrast, contrast-to-noise ratio (CNR), and generalized contrast-to-noise ratio (gCNR) values, measured as 5.72 dB, 1.54, and 0.841 dB, respectively whereas θ-even yielded 5.58 dB, 1.51, and 0.814. Consistent with the phantom findings, In vivo imaging of carotid artery also demonstrated that the PW-PBSF can provide improved resolution of plane-wave images without incurring redundant computational costs.
